Martha S. Cyert Office: 410B Bass Biology

Martha received her A.B. from Harvard University, Ph.D. from UCSF (Marc Kirschner lab), postdoc at UC Berkeley (Jeremy Thorner lab) and joined the faculty of the Stanford Biology Department in 1992 as an Assistant Professor. Currently, she is Associate Chair of the department and serves as the Dr. Nancy Chang Professor and Thomas W. and Susan B. Ford University Fellow in Undergraduate education.  Martha directs the NIH-funded graduate training program in Cellular and Molecular Biology, and serves on the Policy Affairs Advisory Committee for American Society of Biochemistry and Molecular Biology. The Cyert lab focuses on elucidating  functions and signaling mechanisms for calcineurin: the only protein phosphatase that is regulated by Ca2+ and calmodulin, and the target of the immunosuppressant drugs, Cyclosporin A and FK506. Since pioneering studies of yeast calcineurin, the Cyert lab recently shifted to studying the human enzyme, and is leveraging the analysis and discovery of calcineurin-binding SLiMs (Short Linear Motif) to gain insights into calcineurin signaling. Outside the lab, Martha enjoys rock-climbing, taking photographs and appreciating beer.


Research Scientist

Jagoree Roy

Jagoree obtained her Ph.D. from Carnegie Mellon University studying pre-mRNA splicing in S. cerevisiae with John Woolford. Her postdoctoral work was with Elizabeth Blackburn at USCF where she uncovered novel telomerase RNA structure-function relationships. After a hiatus involving motherhood, Jagoree returned to science with a short postdoctoral stint with David Botstein, before joining the Cyert Lab as a research scientist where she has completed fifteen years! Her work has focused on understanding substrate recognition by calcineurin via PxIxIT- and LxVP- SLiMs and exploring new physiological roles for calcineurin, first in yeast and then in mammalian cells. Jagoree also takes an active role in mentoring students in the lab. Outside of the lab, Jagoree enjoys spending time with her husband, chafing her sons who have flown the coop for college and visiting the nearest California coastline at every opportunity.



Callie Wigington

Callie obtained a B.S. in Chemistry from Georgia Southern University (Go Eagles!) and a Ph.D. in Biochemistry, Cell and Developmental Biology (BCDB) at Emory University. As a graduate student in Anita Corbett’s lab, she focused on characterizing disease-relevant targets of RNA-binding proteins and discovered a deep love for quality control events that happen at the nuclear pore. In the Cyert lab, she is focused on characterizing a newly-discovered role for CN at the nuclear pore complex. Callie is also very passionate about effective science communication (both inside and outside the classroom) and serves on the Public Information Committee (PIC) for ASCB. Outside the lab, she enjoys going to the farmer’s market, cooking, drinking wine with her friends, and doing anything outside with her family!


Idil Ulengin

Idil received her B.S. from Sabanci University in Istanbul, Turkey with a major in Biological Sciences and Bioengineering and a minor in Chemistry. She studied with Tina Lee at Carnegie Mellon University for her Ph.D. work on atlastin, the ER dynamin-like protein. Currently, Idil is examining the localization and function of the membrane-associated CNß1 isoform, and is discovering roles for dynamic palmitoylation-depalmitoylation to regulate this enzyme. When not in the lab, Idil enjoys cooking and exploring the SF Bay area.


Jamin Hein

Jamin was awarded a B.S. in Molecular Life Science from the University of Hamburg in Germany, and his Ph.D. in Molecular Medicine from the University of Copenhagen in Denmark. He studied mitotic mechanism and regulation with Professor Jakob Nilsson at the Novo Nordisk Foundation Center for Protein Research. Jamin is currently a Bio-X Novo Nordisk Visiting Scholar at Stanford with the Cyert and Fordyce labs and is examining peptide-protein interactions using the MRBLE-Pep technology (Nguyen et al. 2019).


Graduate Students

Shein Ei Cho

Shein received her B.S. in Biology from Agnes Scott College and gained research experience working as a research technologist at St. Jude Children’s Research Hospital. She will receive her master's degree in Biology from Stanford in summer, 2019. Shein is passionate about science outreach, and interned at the Tech museum in San José. Originally from Myanmar, Shein is currently developing a mobile science curriculum for the Myanmar Mobile Education Project that uses the inexpensive foldscope microscope invented by Manu Prakash, Stanford Department of Bioengineering.


Eirini Tsekitsidou

Eirini was born in Greece. She obtained a B.A. in Biology from Smith College in Northampton, MA. While there, she studied filarial nematodes of marine mammals in the lab of Steve Williams. She is currently a graduate student in Cell and Molecular Biology at Stanford. In the Cyert lab, she is interested in identifying calcineurin’s role in the context of the cell cycle and centrosome. She also enjoys mentoring undergraduate students in the Stanford Science Research Program (SSRP). Outside the lab, she likes spending time with cute animals, traveling and trying new restaurants.


Devin Bradburn

Devin is a Longhorn! He received his B.S. in Biochemistry from the University of Texas, Austin where he studied enzymes that resolve G4 quadraplexes in DNA/RNA with Rick Russell. Devin joined the Stanford Biosciences Ph.D. program in 2017, and his project in the Cyert lab is determining the function of C16Orf74, an uncharacterized ORF that binds calcineurin and targets it to membranes. Devin is an avid audiobook listener and enjoys rock climbing.
