Post-Doctoral Fellows 

Mehdi Pirouz Headshot

Mehdi Pirouz, PhD

Mehdi received his PhD from Goettingen University, Germany (Max Planck Institute for Biophysical Chemistry) in 2013, during which he studied germ cell development and pluripotency in mouse embryonic stem cells. He also worked on the role of BAF chromatin remodeling complexes in brain development. Mehdi started his postdoctoral training in March 2014 in the Gregory lab and he is interested in the role of noncoding RNAs in stem cells, development and diseases.


Qi Liu, PhD

Qi received his PhD degree in 2017 from Chinese Academy of Forestry, Beijing, China and afterwards joined the Gregory lab. He is currently working on RNA bioinformatics, as well as studying RNA post-transcriptional regulation using computational methods.




Esteban Orellana, PhD

Esteban joined the Gregory laboratory in May 2018. He completed his graduate studies at Purdue University.  His project involved ligand-mediated miRNA delivery and miRNA combinatorial therapeutics for cancer. Esteban's current research focuses on RNA methylation and its role in gene regulation and cancers including glioblastoma and sarcomas.



Jia Cui, PhD

Jia received her PhD in 2018 from the University of Alabama at Birmingham, where she studied the post-transcriptional regulation of anti-apoptotic protein MCL1 in cancer. In August 2018 she joined the Gregory lab as a postdoctoral fellow and has been interested in the field of RNA biology. Jia's current research focuses on RNA modifications and their roles in gene regulation and cancer.


Jiazhi Li headshot

Jiazhi Li, PhD

Jiazhi received her PhD in 2018 from Institute of Biophysics, Chinese Academy of Sciences. Her doctoral program focused on structural and mechanistic basis of the CRISPR-Cas system. She joined Gregory Lab in April 2019 and started her research on investigating mechanisms of posttranscriptional gene regulation in a structural and functional combining method.



Lab Manager
