Austin Humphries

Assistant Professor

I am interested in ecological and social outcomes that arise from fisheries and coastal management, including aquaculture. I conduct field and lab experiments as well as engage in socioeconomic interviews, perform synthetic statistical analyses, and design simulation models to understand these coupled interactions. My group and I study these problems using a holistic ecosystem approach, where we consider habitat and species interactions along with environmental drivers and human dimensions. We work in a variety of coastal marine ecosystems and are motivated to find ecologically and socially appropriate solutions rooted in sustainability principles. 

I currently hold a joint appointment at URI with the College of Environment and Life Sciences and the Graduate School of Oceanography. Before starting at URI in 2015, I completed a Postdoctoral Fellowship at the US Environmental Protection Agency. I finished my PhD at Rhodes University (South Africa) in 2014 where my research was based in Kenya and in collaboration with the Wildlife Conservation Society. I earned a MS degree at Louisiana State University, and a BS degree at the University of Vermont. I grew up in the mountains of southwest Virginia and I enjoy fishing, surfing, camping, and tinkering in the garage.

I use genomic tools to better understand the appropriate scales for conservation and management of coral reef ecosystems. Within this field, I study co-evolution in corals and their algal symbionts, connectivity among marine populations, the effectiveness of marine protected areas, and how commercial fish species have changed through time due to fisheries. My research here at URI applies these concepts to the Indonesian coral reef system to better understand how management may reconcile objectives based on biodiversity and/or fisheries benefits.

Before joining the URI family, I completed a postdoctoral research at the University of Puerto Rico and the PR Department of Natural Resources working with the genomics of the Queen Conch. Before then, I completed my PhD studying coral reef fish connectivity across the Caribbean and my MS working with Cobia aquaculture. I’m from Bogotá, Colombia, and have a love for the Andes, beaches, diving, traveling and camping.

My current research interests are in characterizing human impacts on coral reef fish assemblages through the synthesis of social and ecological data. At URI, I am applying this framework to the coral reef ecosystems of Indonesia. Before Rhode Island, I worked for NOAA’s Pacific Islands Fisheries Science Center in Hawaii, where I split my time between the office and being out to sea, collecting integrated ecosystem monitoring data throughout the U.S. Pacific. I finished my PhD in 2013 at the University of Hawai‘i at Mānoa studying spatial patterns of coral genetic relatedness. Before graduate school, I earned a BS from Cornell University and worked with a community-based coastal resource management NGO in the Philippines as a U.S. Fulbright Scholar.

As you can see, my research interests may have shifted slightly over the years, but I remain committed to building capacity where it is needed, both domestically and internationally, in coral reef conservation and ecosystem-based fisheries management. I enjoy running, surfing, cooking, playing piano, and listening to music. I grew up on Long Island, New York, and am happy to be returning to the East Coast.

The goal of my research is to inform ecosystem-based management of fisheries in my home country of Ghana. Specifically, the focus of my PhD work is on modeling fish and fisheries effects of spatial and seasonal closures for the nearshore sardine fishery in Ghana. I am collecting fish landings data from across the coast in 8 different locations with help from collaborators at University of Cape Coast. I am also very excited and interested in attending scientific conferences and improving my communication of research.

Before coming to URI, I attended the University of Cape Coast (Ghana) and graduated in 2013 with a MS in Aquaculture and a BS in Fisheries and Aquatic Sciences in 2009. For my MS thesis, I examined aspects of the biology and ecology of black-chinned tilapia in the Dominli lagoon of Ghana. I am originally from Jaway in the Jomoro District of Ghana and when I am not in the field or classroom, I enjoy reading and playing soccer.

My interests are in marine spatial ecology, population dynamics, and fisheries management. My PhD work focuses on exploring ecological outcomes of different gear-based fisheries management strategies for small-scale coral reef fisheries in Indonesia. I will create a simulation model used for ecosystem-based management and the fieldwork includes underwater surveys as well as recording fish being caught on the coral reefs in Nusa Tenggara Barat, Wakatobi, and Raja Ampat in collaboration with local universities.

I completed my MS and BS degrees at California Polytechnic State University, San Luis Obispo. For my masters thesis, I evaluated the effectiveness of periodically-harvested fisheries closures in Fiji. Also during my undergraduate studies, I was a research technician for the California Collaborative Fisheries Research Program. I am from southern California and when I'm not coding models I enjoy diving, surfing, fishing, and traveling.

I have research interests in demersal fisheries, data-poor stock assessments, and collaborative fisheries data collection methods. For my PhD research, I want to better understand the ecological aspects of the Indonesian deepwater snapper-grouper fishery and test management strategies through simulation modeling. I will also be investigating vessel dynamics using Bayesian approaches. My fieldwork is across eastern Indonesia in collaboration with Dr. Peter Mous at The Nature Conservancy.   

I graduated with a BS from Wellesley College in 2013. Following graduation, I worked for The Nature Conservancy's Indonesia Fisheries Program to establish collaborative data collection systems with fishers and boat captains. This work enabled us to pinpoint specific coordinates for each fish being caught and led to my PhD dissertation research. I grew up in Java, Indonesia, and before moving to Rhode Island I lived in Bali where I would divide my time between work and triathlon training.

My primary research interest is aimed at improving coastal fisheries management in my homeland of Indonesia. For my MS, I will be researching the community life histories and ecological effects of spatial zoning and gear-restrictions in the coral reefs of the Sunda-Banda Sea in Indonesia. This research is in collaboration with the World Wildlife Fund of Indonesia.

While doing my MS, I simultaneously hold a position in the Directorate General of Capture Fisheries in the Ministry of Marine Affairs and Fisheries of Indonesia (MMAF). Before my position at MMAF and coming to URI, I completed a MS degree at Vrije Universiteit Brussel in Belgium. I earned my BS degree at Bogor Agricultural University in Indonesia. I am from Tangerang on the island of Java, Indonesia, and I enjoy gardening and playing badminton when I'm not at the mosque or cooking delicious Indonesian food for the lab.

The goal of my masters research is to update and revise the reproductive parameters of the Blue Shark, including re-examining the migration routes as they relate to reproductive conditions. I am conducting this work in collaboration with Dr. Lisa Natanson at NOAA's National Marine Fisheries Service (NMFS) lab in Narragansett, RI. This research will inform population dynamics models for the Blue Shark in the northern Atlantic Ocean. 

I graduated from URI in 2015 with a BS in Marine Biology. Since then, I have worked on a sport fishing boat and also volunteered at NOAA-NMFS. In these roles, I have helped collect reproductive data on sharks by traveling to fishing tournaments in the Northeast region. I grew up in Oakland, New Jersey, and I enjoy free diving, snowboarding, and anything on the ocean.

I am interested in addressing data and communication gaps in tropical fisheries management. My thesis work analyzes the social-ecological impact of rabbitfish and grouper fisheries in eastern Indonesia, focusing on the Bajou community in Wakatobi. This research will help us better understand how fisheries benefits interact with social, cultural, and economic factors that affect the distribution of reef-derived seafood. Fieldwork for this project is being done in collaboration with Dr. Wa Iba at the University of Halu Oleo in Kendari, SE Sulawesi. 

Before coming to URI, I worked as a public radio journalist in Southeast Alaska before moving to Indonesia where I reported on environmental issues for Scientific American, Al Jazeera, Mongabay, and other outlets for many years. I graduated from Reed College in 2009 with a BS degree in Biology. I was born in Jakarta and grew up in Beijing, Bangalore, and other cities in South and East Asia. I enjoy hiking and learning new languages.

My research interests include marine spatial ecology, marine protected areas, and integrated aquaculture systems. For my Master’s research, I am determining the optimal growth conditions for kelp in integrated multi-trophic aquaculture (IMTA) systems around Rhode Island. I am analyzing the abiotic conditions at study sites and how they influence the bioenergetics of both kelp and oysters to create production potential maps for the aquaculture industry. I am glad to be working to support local sustainable food systems.

I graduated from Smith College in 2017 as a double major in Biological Sciences as well as Environmental Science and Policy. Since graduating, I have worked for the Maria Mitchell Aquarium in Nantucket, Massachusetts, and The Ecology School in Saco, Maine, expanding my skills as an environmental educator and science communicator. I grew up landlocked in Williamstown, Massachusetts, but still managed to find a love for all things ocean. I enjoy exploring outdoors, all sorts of dance, cooking, and knitting.
