Todd Lab members

Principal Investigator:

Peter K. Todd, M.D., Ph.D.


Peter is an Associate Professor and the Inaugural Bucky and Patti Harris Professor of Neurology. He earned a Bachelor of Science degree from the University of California, San Diego and then entered the Medical Science Training Program at the University of Wisconsin, where he completed his doctorate and medical degree. His Ph.D research focused on synaptic defects in Fragile X Syndrome, a common inherited cause of cognitive impairment in children. He completed a neurology residency at the University of Pennsylvania where he did research on the role of the ubiquitin proteasome system and autophagy in neurodegeneration with Dr J. Paul Taylor. He came to Michigan in 2008 as an American Academy of Neurology clinical research fellow and trained in the laboratory of Henry L. Paulson, M.D., Ph.D., in the Michigan Institute for Neurodegenerative Disease. Dr. Todd Joined the Michigan faculty in 2010. When he is not in the lab, Dr Todd sees adult patients with Fragile X-associated disorders (Fragile X Syndrome, FXTAS, FXPOI) and Cerebellar Ataxia at the University of Michigan. He also sees movement disorders patients at the Ann Arbor VA Medical Center. Peter spends his free time with his wife and daughters. He is an avid road cyclist, hiker, canoeist and music enthusiast.

Geena joined the Todd lab as a post-doctoral fellow in the summer of 2017. She obtained her Ph.D. in Neuroscience with Stephanie Ceman at the University of Illinois. She is now pursuing research aimed at reactivating the Fragile X locus and understanding the pathogenesis of age related neurodegeneration.

Indranil Malik, Ph.D.


Indranil joined the Todd lab as a postdoctoral fellow in the fall of 2017 after finishing his Ph.D. in Biochemistry and Biophysics with Craig Kaplan at Texas A&M University. He is exploring the roles of RNA structure in repeat expansion disorders.

Caitlin Rodriguez, Ph.D.


Caitlin was a Neuroscience Graduate student who joined the lab in 2013 and defended her thesis in March 2018. She obtained her undergraduate degree from UCSD where she trained with Tracy Johnson. She is focusing on translational initiation mechanisms in neurons and their roles in plasticity and disease.

Katelyn is a Cell and Molecular Biology student who joined the lab in 2015. She obtained her undergraduate degree at Yale. She is interested in RAN translation at C9orf72 associated GGGGCC repeats that cause ALS and FTD.

Yi-Ju(Lulu) Tseng


Lulu is a master's student who joined the lab in 2016. She is working on identifying inhibitors of RAN translation.

Shannon Wright


Shannon is a Neuroscience Graduate student who joined the lab in 2017. She obtained her undergraduate degree in Biochemistry from Kenyon College. She is working with stem cell models of Fragile X-associated disorders and Bioinformatic analyses of large datasets.

Yuan Zhang


Yuan is a Neurologist who is visiting as part of her Ph.D. program at Xiangya Hospital at Central South University, China. She joined our group in 2017. She is developing better methods of detecting and measuring RAN translation products.

Lab Manager:

Amy Krans


Amy has served as primary research support staff to the Todd Lab since 2010. She received her Bachelor of Science degree from Grand Valley State University in Biomedical Science and then earned a Master of Science degree from Purdue University in Medicinal Chemistry and Molecular Pharmacology.


Rebecca Stone


Rebecca Serves as the primary administrative Assistant to the Todd lab and other UMIND labs.


Bertha is a new lab member whose project involves filling the space left by Peter whenever he is out of the lab while providing the same cool demeanor.

University of Michigan Initiative on Neurodegenerative Diseases: (UMIND)

The Todd lab is part of a larger group of Neurology research labs focused on Mechanisms of Neurodegeneration. These include the laboratories of Dr. Henry Paulson, Dr. Vikram Shakkottai, Dr. Sami Barmada, Dr. Dan Leventhal, and Dr. William Dauer. All of these labs share common space as well as certain equipment and all the labs interact intellectually and socially.
