Research Molecular Biologist:


toddTodd Greco, PhD

PhD @ U Penn

Princeton, 2009 - present

A biochemist and neuroscientist by training, Todd returned to his home state of New Jersey in 2009 to join the Cristea lab for his postdoctoral work. Currently a Research Molecular Biologist, he works on multidisciplinary projects that harness mass spectrometry and bioinformatics to study the dynamics of protein complexes. When he’s not studying how protein interactions influence the development of Huntington’s disease, he’s mentoring students in the principles of proteomics and biochemistry. In his spare time, Todd enjoys cooking simple yet flavorful meals while pondering the art of mass spectrometry maintenance.

Postdoctoral Scientists:


jaimeJosiah E. (Jaime) Hutton, PhD

PhD @ Vanderbilt University


After surviving the humidity of Florida, the country music of Tennessee, and the brutal winters of Illinois, Jaime moved to New Jersey to further advance his training in analytical proteomics and to learn virology in the Cristea Lab. When not babysitting the mass spectrometers, Jaime enjoys exercising, board games with his friends, and giving attention to the best cat in the Cristea Lab.


joshJoshua L. Justice, PhD

PhD @ University of Alabama at Birmingham


Joshua completed his Ph.D in Virology from the University of Alabama at Birmingham (where he was born and raised) and joined the Cristea lab in 2019 to study how viral infections are detected and combated by the host cell. Joshua enjoys gardening, fine whiskey, and the occasional D&D campaign with his labmates.


John MuroskiJohn Muroski, PhD

PhD @ University of California Los Angeles


Coast hopping from New York to California and back to New Jersey, John looks to learn skills in virology and cellular biology in addition to further advancing his skills in mass spectrometry and proteomics. 


xinleiXinlei Sheng, PhD

PhD @ Princeton University


Xinlei, who leveled up with a Bachelor’s degree of biological sciences in Tsinghua University, is a unique electric-type pokemon introduced to Princeton in 2014. Xinlei recently evolved into a doctor and is continuing in the Cristea Lab as a post-doc. You could also find Xinlei playing basketball, dismantling electronic devices, and taking photos of other pokemons in the wild area.



Lum.KrystalKrystal Lum, PhD

PhD @ Princeton University


From Queens, New York, Krystal is pursuing her longstanding interests in intrinsic and innate immunity using an interdisciplinary approach. Krystal has an affinity for bunnies and rescuing animals in need, fossil hunting, rockhounding, road cycling, playing Scrabble, puzzling, and landscape sketching.



Graduate Students:


BokaiBokai Song

Undergrad @ Tsinghua University
China Scholarship


Bokai is from Tianjin, China, and did his undergrad in Tsinghua University in Beijing before coming to the Cristea lab to pursue a PhD. He studies the function and regulation of the DNA sensor cGAS in innate immune signaling. Outside the lab, Bokai is a guitar and ukulele player.



Cora BetsingerCora Betsinger

Undergrad @ University of Wisconsin, Madison
NIH F31 Research Fellowship (NIAID)
AHA Predoctoral Fellowship Recipient


A lover of all things mitochondria, Cora is working to understand the battle between HCMV and host cells for control over cellular metabolism during infection. In her free time she loves hiking, camping, canoeing, trying new restaurants, knitting, and hanging out with her hamster (Sebastian).


katelynKatelyn C. Cook

Undergrad @ University of Colorado, Boulder
Princeton Centennial Award
NIH F31 Research Fellowship (NIAID)
ASCB Porter Prize for Research Excellence (Graduate) 2021
Making her way east from California, Nevada, Colorado, and finally to New Jersey, Katelyn is pursuing a PhD focused on exploring how intracellular pathogens remodel organelles to achieve infection. When she’s not at the bench, Katelyn fills her time with trail runs, gardening, strategy RPGs, cooking (pun intended), and cuddles with her cats.


timTimothy Howard

Undergrad @ University of Colorado, Boulder


Tim comes from the great state of Colorado. His PhD work focuses on the relationship between virus and host and, more specifically, how host cells recognize viral DNA to activate vital antiviral programs. Outside of lab, he enjoys playing rec softball and ice hockey, and you can often find him hanging out at local breweries or the beach in the summer.


michelleMichelle Kennedy

Undergrad @ University of Colorado, Boulder
NSF Graduate Fellowship


In an unexpected turn of events, Michelle has become the resident coding guru of the lab and focuses on discerning biological meaning from large datasets. As a transplant from Colorado, when not glued to her computer and keyboard she enjoys exploring the outdoors, investigating the NJ craft brewery scene, and cuddling with her cats.


daweiDawei Liu

Undergrad @ UC Berkeley


After finishing his undergraduate work at UC Berkeley, Dawei came to Princeton to pursue his PhD. He focuses on the interactions between host and viruses, specifically how cells are able to sense invading viruses and mount effective innate immune responses. Dawei is a pro at badminton and an avid video game and board game player too!


will-hofstadterWilliam Hofstadter

Undergrad @ Northwestern University


Coming to Princeton from the Midwest and California, Will studies how viruses manipulate fundamental cellular processes. Outside of the lab, Will also enjoys exploring the outdoors, swimming, and reptiles.



Matt_non-mustache    Matthew Tyl

     Undergrad @ University of Michigan



Hailing from the great state of Michigan, Matt is a lover of all posttranslational modifications (PTMs). He is investigating host-virus interactions at the PTM regulatory interface, focusing on sirtuins and novel PTMs. Outside of the lab, he enjoys exercising and playing games with friends.


Peter MetzgerPeter Metzger

Undergrad @ Georgetown University

Hailing from Minneapolis and Washington D.C., Peter is most interested in how virus-host interactions drive rearrangements in organelle structure and immune signaling during infection. In his free time, he enjoys playing guitar, golfing, and baking high-fat confections.



Tavis ReedTavis Reed

Undergrad @ Washington University in St. Louis


Originally from Illinois, Tavis came to Princeton to pursue his PhD. He is interested in developing computational tools for proteomics and is co-advised by Olga Troyanskaya. In his free time, he enjoys being bad at video games and sleeping in late.






eleneElene Tsopurashvili

Princeton '22



Originally from the Republic of Georgia and now living in Philadelphia, Elene found a new home in Cristea lab. Here she works to characterize structural and functional changes in ER-mitochondria contact sites during infection. Outside the lab, you will find her advocating for low-income students on campus, reading global health news and chatting with her grandparents about gardening, Princeton adventures, and everyday life.



brettBrett Phelan

Princeton '22


Hailing from St. Louis, Brett’s research in the lab focuses on host protein dynamics during viral infection. A recovering math major, Brett hopes to one day unite his love for math and biology in a career as a researcher. Outside of the lab, Brett enjoys tasteful pop music and the company of his dogs.
