Jacob Allgeier  

Assistant Professor 

Department of Ecology and Evolutionary Biology

University of Michigan

jeallg "at" umich.edu


Jake is an ecologist with broad interests in how human-induced changes alter ecosystem processes and the services that they provide.  His work is rooted in basic ecological theory, but motivated by increasing need for food security, particularly in coastal societies. 

Jake has won international acclaim for his ability to sit on porches, stoops, and random curbsides in any given country. 

Maximilian Hesselbarth (he/him/his)  - Postdoc

Personal Homepage

Max is a computational ecologist interested especially in the spatially explicit characteristics of ecological processes. Max attended the University of Goettingen for his bachelor’s and master’s degree as well as his PhD. During his PhD research, Max used individual based simulation modelling and point pattern analysis to infer underlying ecological processes from spatial patterns. Furthermore, Max is an R enthusiast and author of several R packages. In his free time Max enjoys all different kinds of outdoor activities and almost all sports that involve a ball.



Bridget Shayka - PhD Student

bshayka "at" umich.edu

Bridget is a PhD student studying nutrient dynamics in tropical marine systems. She attended the University of Virginia as an undergraduate, and completed her masters at California State University, Northridge studying the impacts of nutrient runoff and ocean acidification on coral reef algae in Moorea, French Polynesia. Her PhD research at the University of Michigan is focused on the effects of nutrients on seagrass communities in the Caribbean and their carbon sequestration ability. Besides snorkeling and scuba diving, Bridget loves hiking and all other water-related activities.

Katrina Munsterman - PhD Student

kmunster "at" umich.edu

Katrina is a PhD student interested in studying the role of fishes in ecosystem processes on disturbed coral reefs. She attended the University of California Santa Barbara for her bachelor’s and master’s degrees and spent nearly a decade researching herbivorous fishes in Moorea, French Polynesia. For her PhD research, she will be working with fishing communities in the Caribbean to better understand the impact of human alterations on ecosystem function. Katrina is a picnic enthusiast and can be found running or cycling, most likely accompanied by her dog, Bandit.


Samantha Iliff - PhD Student

siliff "at" umich.edu

Sammy is a PhD student studying community and ecosystem ecology in coastal marine systems. She completed her B.S. at Florida Atlantic University in marine biology and mathematics while researching the impacts of pesticide pollution on oyster reef communities for her thesis and studying deep water coral nurseries in Honolulu, HI as an undergraduate NOAA Hollings Scholar. Her PhD research is focused on invertebrates and the effects of habitat structure on energy flow through seagrass food webs. If she isn't underwater or in the mountains, Sammy enjoys playing volleyball, illustrating, and traveling the world in search of it's greatest sandwich. 


Shreyann Seth - UROP Student

Hi! My name is Shreyaan and I’m a freshman in the LSA Honors program hoping to major in Ecology, Evolution and Biodiversity. I am originally from Davenport, Iowa but have spent the last 15 years growing up in India. I am working on the project ‘Marine Ecology and Biodiversity: Examining Invertebrate Communities from Bahamas and Florida Seagrass Beds’ as part of my first year UROP experience! I hope to use this time to familiarize myself with the scientific research process, and hopefully begin my journey to becoming a researcher myself! I love traveling, exploring parks and trying new foods! 

Natalie Walton - UROP Student 

Natalie is a first-year undergraduate student studying biochemistry at the University of Michigan. She is very interested in researching the effects of ocean acidification and warming on seaweeds and algal turfs. Additionally, she is intrigued by coral reefs and the detailed yet delicate relationships within them. When she’s not in a tree, you can find Natalie searching for the comfiest fleece jacket or falling off of a paddle board. 

Charlie Kotila - Undergraduate Researcher 

Charlie is a fourth year undergraduate student majoring in ecology, evolution, and biodiversity and minoring in oceanography. He is an interdisciplinary researcher working with both the Allgeier lab and Julia Cole’s climate lab at Michigan. Charlie is studying phosphorus time-series from corals in the Galapagos. Outside of school, Charlie is interested in hiking, soccer, and Michigan sports.
