Austin Humphries

Assistant Professor

I am interested in ecological and social outcomes that arise from fisheries and coastal management. I conduct field and lab experiments as well as engage in sociocultural interviews, perform synthetic statistical analyses, and design simulation models to understand these coupled interactions. This work is both local and international, often studying oysters in estuaries and tropical coral reef fishes, as well as the human dimension aspect which involves the people that depend on these resources. 

Before coming to 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. My doctoral research was based in Kenya and in collaboration with the Wildlife Conservation Society. Before my time in Africa, I earned a MS degree at Louisiana State University in 2010, and a BS degree at the University of Vermont in 2006. 

I grew up in the mountains of southwest Virginia and in my free time I enjoy fishing, surfing, and being outside. 


Diky Suganda

PhD student

My primary research interest is aimed at improving coastal fisheries management in my homeland of Indonesia. For my PhD, I will be researching the ecological effects of indigenous and government spatial planning in the coral reef fisheries of Indonesia. I am doing my field work and monitoring in Raja Ampat, West Papua, Indonesia.

While doing my PhD, 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.


Evans Arizi

PhD student

The goal of my research is to provide data to inform ecosystem-based management of fisheries in my home country of Ghana. Specifically, the focus of my PhD work is on modeling fisheries effects of spatial and seasonal closures for the sardine fisheries in Ghana. 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.


katie viducic

MS student

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 will conduct this work in collaboration with Lisa Natanson at NOAA's National Marine Fisheries Service lab in Narragansett, RI.

I graduated from URI in 2015 with a Bachelor’s degree 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 traveling to fishing tournaments in the region.

I grew up in Oakland, New Jersey, and I enjoy free diving, snowboarding, and being on the ocean.


Paul Carvalho

PhD student

I am interested 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.

Before coming to URI, 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.


Elle Wibisono

PhD student

I am interested in data-poor stock assessments of demersal fisheries. For my PhD research, I want to better understand the ecological aspects of this multi-species fishery and test management strategies through simulation modeling. 

I graduated with a BS from Wellesley College in 2013. After this, I worked for The Nature Conservancy's Indonesia Fisheries Program to establish collaborative data collection systems with fishers in the deepwater snapper-grouper fisheries. This work enabled us to pinpoint specific coordinates for each fish being caught.

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. 


Melati Kaye

MESM student

I am interested in addressing data and communication gaps in tropical fisheries management. My thesis work analyzes the impact of different fishery management systems on reef ecology and coastal livelihoods in Eastern Indonesia.

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. 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.
