Maria Stager, PhD (PI)Maria was born and raised in the Finger Lakes of central NY. She attended Cornell University and spent a semester studying in Italy. After college, she stumbled into bird research -- working as a research assistant for projects in Argentina, Australia, and the Galapagos, among other places. This eventually led to grad school. Maria did her graduate work with Zac Cheviron, first as a Master's student at U. of Illinois at Urbana-Champaign and then as a PhD student at U. Montana. She then postdoced at U. South Carolina and later with Scott Taylor at CU Boulder under an NSF PRFB. Maria joined the faculty at UMass Amherst as an Assistant Professor in Fall 2022. She feels extremely fortunate to be working with such a wonderful group of people! She spends her free time with her dog, Oliver.

Paul Dougherty, PhD (Postdoc)Paul joined the lab as an NSF Postdoctoral Research Fellow in Biology in Jan 2024. Before joining us, Paul received his B.A. from Colby College and completed his PhD at the University of Wyoming where he studied molt-migration and hybridization patterns in Passerina buntings. Paul is continuing this work at UMass and is deploying geolocators on Lazuli Buntings to track migration patterns, as well as performing acclimation experiments to investigate both the environmental cues and the underlying expression patterns that regulate molt in these birds. He is co-mentored by Nathan Senner.

Akshiti Bhat (PhD Candidate)Akshiti is a graduate student in the Organismic & Evolutionary Biology Program. She joined the lab in August 2024 after completing both her B.S. and M.S. at the Indian Institute of Science Education and Research in 2023. Akshiti has experience studying social networks in mixed species flocks of the Himalayas and is now applying those skills to look at interactions between an individual's physiology and social foraging behavior in our local winter flocks. She is eager to learn every technique so she can make use of them in her dissertation work. Akshiti holds a Fox Fellowship from the College of Natural Sciences to support her graduate research.

João Climaco (PhD Student)João is a graduate student in the Organismic and Evolutionary Biology Program. He is joining the lab in Fall 2025, having just finished his Masters at the Universidade Estadual de Santa Cruz in Brazil. For his Masters, he studied the ecophysiology and evolution of lizards in the Atlantic Forest of Brazil. Prior to that, he completed his BS at São Paulo State University, where he helped establish cell culture in cavefish. João's dissertation work will focus on physiology and evolution of juncos but we are excited for him to bring a host of knowledge about non-avian reptiles to the lab!

Serina Suzuki (PhD Candidate)Serina is a graduate student in the Organismic & Evolutionary Biology Program. She was awarded an inaugural Quad Fellowship from the federal government to support her graduate research. Serina completed her undergraduate work at Hokkaido University in Japan where she studied epigenetic mechanisms of avian song learning. She later worked with folks at Nagoya University on breeding and movement patterns of Black-tailed Gulls. Serina is interested in migratory decision making and plans to make use of genomic and transcriptomic techniques in her dissertation work. She is currently perfecting the use of immunohistochemistry techniques in junco brains, but she has a particular fondness for Blue Jays. She's also our resident artist, helping to beautify the lab with her artwork.

Wentao Yang (Masters Student)Wentao is a graduate student in the OEB program. He completed his BS at UC Davis in 2023 and spent the next year working on various field projects as a technician, including work with seabirds, shorebirds, and songbirds, which took him all over the country from Alaska to South Carolina! He joined the lab in August 2024 as a tech for our project with mixed-species winter flocks, before deciding to stay for a Masters, beginning Fall 2025. To add to his top-notch bird banding and handling skills, as well as his tech savvy, Wentao is now learning molecular and physiological techniques. Wentao is also a passionate birder -- he hosts a birding podcast in Mandarin and helped found Birdwatching Clubs both in China and at UC Davis -- and an excellent photographer -- with a photo recently featured in Living Bird.

Yousuf Al Attar (Undergraduate Researcher)Yousuf is a Biochem & Molecular Bio major ('26) in the Honors College. He joined the lab in Fall 2023 and was awarded a Lee SIP scholarship in Summer 2024. Yousuf has learned many wet lab techniques, from DNA and RNA extractions, to PCR and qPCR, to gel electrophoresis, Western blots, and enzyme assays. He presented some of his work at the Summer '24 REU Poster Symposium. He's very efficient and also very organized, so he's often seen teaching other lab members these many techniques. It's absolutely impossible to encounter Yousuf in the lab without a smile on his face! He is also an RA in the dorms, a TA for several classes, and has worked at the Translation Center on campus and is fluent in Arabic. Yousuf will attend optometry school in Fall 2026.

Jason Gehring (Undergraduate Researcher)Jason is Biology major ('26) in the Honors College who joined the lab in Fall 2024. Jason is learning both field and lab techniques. For his senior thesis, Jason is interested in understanding whether winter foraging flocks are composed of related individuals. To that end, he is reconstructing social foraging relationships for chickadees visiting our RFID feeder array and using microsatellites to assess genetic relationships among these same individuals. Jason has additionally spent his past two summers in Alaska working trail crew and fighting wild fires. After he graduates, Jason hopes to pursue graduate school in Biology, perhaps with a focus on behavior and bioacoustics. But first, he'll be headed to Peru to study parrots as a field assistant for the Tambopata Macaw Project!

Charles Lock (Undergraduate Researcher)Charles is a junior Biology major ('27) that joined the lab in Spring 2025 after taking Maria's Physiology course. Charles opted to perfect their wet lab techniques with a project focused on thermal receptor gene expression throughout the junco brain. With Serina's guidance, they have learned to cryosection brains, extract RNA, and perform cDNA synthesis and qPCR. Charles is considering a career in research after graduation.

Matt Santos (Undergraduate Researcher)Matt is a junior Biology major ('27) that joined the lab in Spring 2025 after taking Maria's Physiology course. He stood out in class because of his positive attitude and incessant smile during lecture -- both characters that he brings to the lab, too. Matt has participated in several different projects in the lab, including aging citizen-science photo observations of Lazuli Buntings and field work in Arizona. More recently, he's been learning wet lab techniques by performing DNA extractions and molecular sexing of wintering songbirds. Matt also works for the Biology Department prepping our teaching labs. He hopes to pursue a career in biotech after he graduates.

Will Scheffel (Undergraduate Researcher)Will is a senior Biology major ('26) that joined the lab in Spring 2025 after taking Maria's Physiology course. Will has participated in several different projects in the lab because he's great at everything we throw at him: from field work and respirometry to cryosectioning, histology, and quantitative dissections. Currently, he is learning to section brains to isolate the hypothalamus and other regions that might be important for responding to environmental cues, building on his previous work quantifying structural changes that occur in the liver in response to cold acclimation. Will is also an EMT and is planning to go to medical school after he graduates, where he hopes to specialize in orthopedics.

Trisha Truong (Undergraduate Researcher)Trisha is a senior Bio major ('26) in the Honors College that joined the lab in Fall 2024. She is quantifying feather growth bars in Lazuli Buntings to understand the speed and duration of molt to pair with migration tracks for these same birds. She is a co-author on a manuscript resulting from this work. She is also assisting in Paul's captive bunting work to understand the cues birds use to molt. Outside of the lab, Trisha is on the executive board for the UMass Amherst Science Olympiad, which is a student-run organization aimed at attracting New England high school students to STEM through an annual science competition. Trisha plans to attend med school after graduation and is busy applying to schools and amassing clinical hours.
