Dr. Yulia Gonskikh, Postdoc Fellow

Yulia obtained her Ph.D. from the University of Bern, Switzerland. Since joining the Liu lab in 2020, her current research interests focus on rRNA modifications. Outside the lab, Yulia enjoys squash, tennis, and traveling.

Awards: Early Postdoc. Mobility fellowship by Heinrich Kronstein Foundation

Dr. Sarai Maria Figueroa Mendoza, Postdoc Fellow

Sarai joined the lab in Dec. 2021, she is working on how rRNA modifying enzymes regulate gene expression via the catalytic- and non-catalytic roles.

Michael Owens, M.S. Graduate Student

Michael is a Ph.D. candidate in the Biochemistry and Molecular Biophysics program. He earned his B.S. in Biochemistry and Molecular Biology from the University of South Carolina, and his M.S. in Molecular and Cell Biology and Genetics from the Drexel University College of Medicine (lab of Dr. Srinivas Somarowthu). His master's work was focused on determining the structure of long non-coding RNAs using chemical probing. His current projects in the Liu lab investigate the structure/function relationships of RNA modifying enzymes and sexually dimorphic RNA helicases. When not in lab, he enjoys baking and training his new puppy Alfie.

Awards: 2020-2021 SBMB Training Grant (T32) appointment

Heidi Elashal, Graduate Student

Heidi is a Ph.D. student in the Biochemistry and Molecular Biophysics graduate group. She grew up in New Jersey and earned her B.S. in Biochemistry from Seton Hall University. Her undergraduate research focused on synthetic organic chemistry in the field of peptidomimetics. Heidi is excited to expand her biochemical toolbox and identify the coordination between different RNA species as part of the Liu lab. Outside of the lab, Heidi enjoys spending time with family and friends, reading, binge-watching tv, and watching movies.

Awards: NSF Graduate Research Fellowship Program

Dr. Praneeth Bommisetti, Postdoc Fellow

Praneeth obtained his PhD from the Chemistry department at the University of Utah and joined our lab in Feb 2024 as a post-doctoral researcher. His research interests are RNA modifications, biochemistry, and cell biology. Outside of the lab, he enjoys hiking and mobile photography.

Dr. Yanze Jian, Postdoc Fellow

Yanze obtained her Ph.D. from the University of Science and Technology of China. She is interested in understanding sex-biased gene regulation. Outside the lab, she enjoys swimming, reading books, and watching movies.

Lab Alumni

Prof. Hui Shen, Ph.D.

Former Postdoc Fellow (2018 - 2023)

Hui had completed his postdoc training and started his lab as a full professor at the China Pharmaceutical University!

Hui obtained his Ph.D. at the University of Science and Technology of China in 2017. He started his postdoc training in the Liu lab at UPenn in 2018 and completed it in 2023.

Robert Jordan Ontiveros, Ph.D.

former Graduate Student (2018 - 2022)

Originally from Southern California, Jordan earned his Bachelor’s in Biology from Cal State Fullerton before joining the BMB graduate group in 2017. Since joining the Liu lab, he has published several articles related to RNA modifications and was awarded an NRSA F31 pre-doctoral fellowship for his thesis research. He usually spends his downtime reading fiction, playing video games, biking, and taking pictures of his precious cat Ellie.

Awards: 2018-2020 SBMB Training Grant (T32) appointment, F31 Ruth L. Kirschstein Predoctoral Individual National Research Service Award by the NIGMS

Julian Stoute, Ph.D.

former Graduate Student (2018 - 2023)

Julian is passionate about studying new topics of RNA biology and expanding this knowledge towards larger pathways and human diseases. He currently studies RNA chemical modifications in terms of their molecular pathways and how they relate to cancer. His interests include skiing and strategy tabletop or card games.

Awards: 2019-2020 SBMB Training Grant (T32) appointment

Amber Yanas

former Graduate Student (2019 - 2024)

Before coming to UPenn, Amber received her B.S. in Biochemistry from Virginia Tech. Amber studied sex-biased, phase-separating proteins and their implications at a molecular level in sex-biased diseases. She is now a Philadelphia resident; however, she was born in Arizona and grew up in New Jersey. When Amber is not in the lab, she enjoys running, cooking, baking, crafting, hanging with friends, and playing with her cat, Cosmo.
