Current Graduate Students

Yuko Stender, M.Sc.

Yuko.pngYuko is a Ph.D. candidate in the department of Geography and HIMB. Her current research interest is in spatio-temporal dynamics of coral recruitment and reef communities in human-impacted landscapes, including reef recovery processes from terrestrial runoff and sedimentation. She has been investigating responses of coral settlement and reef communities to water quality and sedimentation in Pelekane Bay, West Hawai‘i. Yuko worked as a graduate research assistant at the Coral Reef Ecology Lab completing her master’s thesis under the direction of Paul Jokiel focusing on changes to inshore marine resources following a shoreline-access closure at Maui’s ‘Āhihi Kīna‘u Natural Area Reserve System, as well as the effects of landscape factors on patterns of coral and coralline algae using the geostatistical approach. She is currently the project lead on a study investigating community recovery from sedimentation at Pila‘a on Kaua‘i.

Angela Richards Donà, M.Sc.

angela_dona_2014.jpgAngela earned her MS in Marine and Atmospheric Science at the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University. She is now pursuing a PhD in the Marine Biology Department at UH Manoa. Angela’s work on the photobiology of the blue Hawaiian Montipora spp. corals with specific focus on determining the functional roles of the chromoproteins that make corals blue, and on understanding whether possession of these pigments favor or hinder blue coral survival under warming seawater scenarios. She aims to use her scientific findings to help the conservation and management of the reefs that have so inspired her and she hopes that through these discoveries, future generations will continue to experience the beauty of these reefs. Visit her website for more information on her background. Her CV can be downloaded here.

Rebecca Weible

ZR0G5640.JPGRebecca has always wanted to be a marine biologist, ever since she could remember. It started with the typical love of dolphins, but soon grew into a fascination for coral reefs and the need to learn how such an intricate and sensitive ecosystem could function as a whole. She went to Castle High School, where she developed a Seagrass trampling project with Mr. Mark Heckman and Dr. Kimberly Peyton. She then went onto the University of Hawaii at Manoa to study marine biology and get involved in many diving activities, such as the Quantitative Underwater Ecological Surveying Techniques (QUEST) course that the Marine Option Program offers. She had the privilege of going on NOAA Research Cruises with the Maritime Archaeology and Fish Teams to the Northwestern Hawaiian Islands and the Main Hawaiian Islands. She is now a Masters student under the direction of Dr. Cindy Hunter.

As part of the Ha’ena CBSFA joint project with DAR, Rebecca will be looking specifically into the resource fish inside and outside the CBSFA for her thesis. She will be looking at the spawning and maximum sizes of these fish and comparing it to data from the past to see whether or not the resource fish of Ha’ena are reaching their reproductive potential. This information will allow the local people who regularly fish these waters to make necessary management decisions in preserving their resource fish.

Ashley McGowan

Ashley grew up in Colorado but always knew she wanted to study the ocean to bring awareness to the many anthropogenic impacts hidden below the surface. In December 2016, she graduated with a B.S. in Marine Biology from the University of Hawaiʻi at Mānoa. Since then, she’s been working on several different projects at the Coral Reef Ecology Lab and interning in the Gates Lab. She is now a Masters student.

 


Lab Staff

Anita Tsang, Lab Manager

IMG_8324.JPG

Being an art major for almost 8 years, it was not until Anita took an environmental science course at Mt. San Antonio College in Southern California that she realized she wanted to help preserve natural ecosystems and make a difference to do something about the lack of knowledge that many people have about the dangers of climate change and overconsumption of resources. She then decided to move to Hawai’i in 2014 and changed her major to Marine Biology, as being in the ocean is when she is most happy. Anita is currently an undergraduate student at the University of Hawai’i at Manoa. She has been a teaching intern for a Biology 172 lab at the university and in summer 2016, she completed her directed research under Dr. Cynthia Hunter and Dr. Ku’ulei Rodgers on coral reef expansion and growth through a process called “calving.” She also conducted sediment analyses and measured reef slope angles on different patch reefs in Kane’ohe Bay, and investigated whether there was a correlation between slope angles and reef size/calf abundance. On top of working at the Coral Reef Ecology lab, she is also currently interning at the Waikiki Aquarium as a coral aquarist. Working with Dr. Sonia Rowley, Erin Kelley, and curator of live exhibits Gwen Lentes, she looks after the deep sea Gorgonian corals and Carijoa riisei. At the aquarium she prepares daily feeds, is responsible for maintenance and photo documentation for research, and is in charge of monitoring and analyzing water quality and nutrients from water samples.

Justin Han, Research Support

Justin.pngJi Hoon Justin Han, international student from South Korea, attended Michigan State University for two and a half years majoring in pre-veterinary science. In 2012, he moved to Hawai’i and decided to change his major to Marine Biology when he realized his passion for the ocean. In summer 2016, he graduated with his B.S. in Marine Biology from the University of Hawai’i at Manoa, and started volunteering at the Coral Reef Ecology Lab under the Optional Practical Training program (OPT). He became familiar with HIMB through the University’s directed research course under Dr. Cynthia Hunter and Dr. Ku’ulei Rodgers. He decided to gain more experience here working in the field and assisting with many different research projects. He is involved with assisting in numerous projects. He hopes to pursue a graduate career investigating climate change effects on algal communities.

Fred Farrell

Fred first came out to HIMB in 1971 at the behest of Dr. Phil Helfrich, who was a classmate of his at Santa Clara University. Over the years, he has helped out with many of HIMB’s most brilliant and famous, the names of some of whom come to mind include people like Dr.s Phil Helfrich, George Losey, Al Catell, Tom Clark, Kim Holland, and for the past sixteen years with Dr.s Ku’ulei Rodgers and Paul Jokiel.

In the year 2000, he went back to college for a while at UH Windward where he completed the routine to qualify for the Marine Options Program Certificate. The years he have participated in the various science projects undertaken at this very special institution have provided the most fulfilling experiences of his life, and he will always consider most fortunate to have had this opportunity. Currently, Fred assists in teaching our staff and student boating navigation and techniques.

Sarah Jane Leicht Severino, Research Associate

IMG_6181

Sarah earned her MS in Marine Science at Hawai’i Pacific University (HPU) in 2015. For her master’s research she developed a technique, the Fluorescence Census Technique (FCT), that utilizes the natural fluorescent pigmentation found within some species of corals to non-destructively census their smallest size classes in-situ under daylight conditions. After graduate school, Sarah worked as a First Mate on HPU’s Research Vessel, Kaholo, for two years. In addition to managing fieldwork on HPU’s Research Vessel, she was recruited by the Navy to manage field operations for a project studying the structure of marine resources within the main Pearl Harbor shipping channel.  The FCT was used in the Pearl Harbor shipping channel to quickly and accurately quantify the abundance and recruitment patterns of juvenile coral colonies on their natural reef substrate.  Since starting in the Coral Reef Ecology Lab, Sarah has been working toward establishing a biological carrying capacity for Hanauma Bay Marine Life Conservation District (MLCD). By analyzing historical data and performing several field experiments, she seeks to quantify changes in the benthic community of reefs at Hanauma Bay in response to pressure from human use.


Interns and Volunteers

 

Anela Garaganza-Tengan

Anela

My name is Nicole Anela Garaganza-Tengan, but you can call me Anela. I was born and raised on the island of Maui, but have been living here on O‘ahu as of 2013. All throughout my life I loved the ocean and all that inhabit it. Free Willy was my favorite movie as a kid and still is, which is where my love for the ocean really came into play. Since watching the movie as a kid, I wanted to grow up to be a whale trainer at Sea World so that I could work with the killer whales. But as I grew older, I had come to realize that the captivity of whales and dolphins was not right. My dream job would be to help in the research of killer whales out in the wild. With that I had set my sights on going to college for Marine Biology. After graduating high school, I did not pursue a degree in Marine Bio right away. In 2012, I graduated and got my AA in Liberal Arts. Following that, I transferred over to the University of Hawai‘i at Manoa in 2013. Since then it has been a roller coaster ride of switching majors from Kinesiology to Family Resources to undeclared. After a couple of years, I decided to take a break from college and focus on work. Then in the spring of 2017, I enrolled into Kapiolani Community College and FINALLY attempted to pursue my passion for the ocean. I am now working on getting my AA in Natural Sciences and am also a part of the Marine Option Program at KCC. As of now I am currently a volunteer here at the Coral Reef Ecology Lab. I enjoy helping out here at the lab and learning more about coral reefs. In the future, I plan to get my bachelors in Marine Biology at either UH or maybe even another university on the mainland.

 

Ashley Fossett

IMG_6171

Ashley earned her B.S. in Biology with an emphasis in ecology from Colorado State University. She grew up with a fascination of deep sea soft corals, hydrothermal vents, and the invertebrates that thrive at these depths. After graduating Ashley took a year off to gain some practical laboratory experience working in a Barley Research Lab for Anheuser-Busch InBev in Fort Collins, Co. She also interned in the marine invertebrate aquarium division of the Butterfly Pavilion in Westminster, CO to gain experience working with corals and other marine invertebrates.

Ashley recently received her Masters in Marine Science from Hawaii Pacific University. She was part of HPU’s applied track, which provides students with a broad-based, in-depth knowledge of physical, geological, chemical, and ecological processes in the ocean as well as a hands-on practicum experience working directly with marine resource management. Ashley came to the Coral Reef Ecology Lab for her practicum. She is investigating percent coral survival in the He‘eia National Estuary Research Reserve (NERR), following the 2015 bleaching event in Kāne‘ohe Bay, Oahu. She has been working with the Hawaii department of aquatic resources (DAR) and NOAA to obtain high definition aerial imagery off the coasts of the Hawaiian Islands that were captured during the 2015 bleaching event. For her project, Ashley performed  ground truthing surveys of the 2015 imagery by conducting 5 meter diameter percent benthic cover surveys (n=60) of the same area in July 2017 while taking GPS coordinates of her survey locations. She then utilized ArcGIS to compare 2017 coral cover in situ with coral cover identified in the 2015 imagery. Ashley also assists in numerous projects for the Coral Reef Ecology Lab.

Kelsey Barnhill

IMG_6180.jpgKelsey Barnhill is pursuing a Masters in Tropical Ecology and Management of Natural Resources from the Norwegian University of Life Science. Originally from San Diego, Kelsey received her Bachelors in Geology with a minor in Marine Science from the University of North Carolina at Chapel Hill. Kelsey is interning at the Coral Reef Ecology Lab while also completing field work for her Masters thesis. Her thesis is focused on changes in coral communities over the past 18 years as well as coral responses to environmental changes in the He’eia watershed. Kelsey’s research interests are tropical reef ecology, deep sea ecology and ocean exploration. She has spent the past two summers sailing on the EV Nautilus and her goal is to one day be a Chief Scientist onboard a research vessel. Kelsey hopes to pursue a PhD upon completion of her Masters. 

 

Tiara Marie Drabble

IMG_6165.jpgTiara joins the lab as part of the Research Experience for Undergraduates (REU) program. She is from American Samoa and currently an undergraduate student at the University of California, Berkeley studying Conservation and Resource Studies. She’s worked as an education outreach intern at both the P.F. Sunia Ocean Center and American Samoa Community College Marine Science Department. She spent a semester at Berkeley’s Gump Station in Mo’orea, French Polynesia studying natural alternatives to combatting crown-of-thorns seastar overpopulation, where she discovered her interest in scientific research and field studies. This summer, her project involves monitoring coral responses to varying lengths of tidal exposure, as well as validating the lab’s newly developed Hawaiian Ko’a Card as a resource to assess coral health.

Rolandon Adde

IMG_6164.jpg

Hi my name is Rolandon Adde and I am from the island of Ebeye in the Marshall Islands. I graduated from the College of the Marshall Islands (CMI) with an AA degree in Liberal Arts in 2017. After I graduated, I started to work with the Marshall Islands Marine Resources Authority (MIMRA) as an intern for 1 and ½ years and accidentally got introduce to the Marine Life and finally attempted to pursue my passion for the ocean. Now in summer 2018, I got my certificate in marine science from the College of the Marshall Islands and I am currently a Research Experience for Undergraduate for the Pacific Islander (REU) intern working with Dr. Ku’ulei Rodgers and Sarah J. Leicht Severino in the Coral Reef Ecology Lab at the Hawaii Institute of Marine Biology. I am conducting a project on how the different classes of parrotfish related to the Rugosity (spatial complexity) in Hanauma Bay vs Pila’a. After this REU program, I am hoping to attend the University of Hawaii at Hilo this upcoming semester, fall 2018, to pursue my B.A in Marine Science.

 


 Affiliate Researchers

Dr. Evelyn Cox

img_8267Dr. Cox was born on Kaua‘i, living in ‘Ele‘ele until her family moved to Honolulu.  She went off to the mainland for college, returning to do a MS at the University of Hawai‘i-Mānoa, where she became a Scientific SCUBA Diver.  Although her PhD was obtained from the University of New Mexico (another beautiful state), her research was done in Hawai‘i on the interactions between coral feeding butterflyfishes and the corals that serve as foods.  Her research continues to revolve around corals and their ecology – current projects focus on a coral disease, Montipora white syndrome in Kāne‘ohe Bay.  The acute form of this disease has now resulted in 2 significant outbreaks and sent me to the 12th International Coral Reef Symposium in Australia in 2012 to report on this new phenomenon.

Dr. John Stimson, Emeritus Faculty

IMG_0491.JPGKāne‘ohe Bay is a convenient setting in which to examine the response of a coral reef community to physical , chemical and biological challenges.  High nutrient concentrations in combination with low abundance of benthic herbivores allowed macroalgae to come to dominate reefs in the Bay for more than 36 years, and led to the development of what have come to be known in the coral reef literature as phase shifts.  Unusual weather conditions brought an end to this dominance and led to a return to coral dominance over the last 10 years.  Recently, however, new macroalgal species appeared to be on the path to dominance of reefs, but a different set of weather conditions, those associated with coral bleaching, appear to have led to the suppression of these algae, but with relatively small cost to coral cover in the Bay.

Dr. Robert Kinzie, Emeritus Faculty

IMG_8314.JPGIslands are, almost by definition, ideal places to study aquatic systems. The Hawaiian Islands, the most isolated archipelago on Earth, provides opportunities to study aquatic systems, both marine and freshwater, from evolutionary, ecological and geomorphological perspectives. Dr. Kinzie’s research takes advantage of these opportunities by focusing on streams, coral reefs and the nearshore environments where these two systems interact.
