Robert Schwabe, MD

Robert obtained his MD and doctoral degree in immunology from LMU Munich, Germany. After his postdoc at UNC Chapel Hill, he was recruited to Columbia University in 2003. His goal is to use innovative approaches to better understand mechanisms of liver disease and develop novel treatments for fatty liver, fibrosis and cancer. Robert is also the inaugural director of Columbia's NIH P30-funded Digestive and Liver Disease Research Center (https://www.columbiadldrc.org). Outside the lab, Robert likes to cook, travel and bike.

Vera Garcia, PhD

Marcella Steffani, MD

Robert Schwabe, MD

Vera obtained her PhD in Molecular Medicine from the University of Santiago de Compostela, Spain. Vera  joined the Schwabe lab  in late 2024.  She combines computational analysis tools with in vivo CRISPRi sceens to uncover to uncover tumor cell - immune crosstalk and novel therapeutic targets in hepatocellullar carcinoma (HCC). Finding liver/HCC-specific approaches and concepts may open up novel treatment options/combinations. Vera is a passionate coffee lover who enjoys discovering new restaurants and coffee spots across New York City.

Marcella Steffani, MD

Marcella Steffani, MD

Marcella Steffani, MD

 Marcella obtained her MD from Marburg University and was trained in general surgery at Technical University, Munich, Germany. Marcella seeks to find novel therapeutic targets in hepatocellular by combining in vivo CRISPR screens and multimodal pharmacologic treatments with single cell-based analysis of transcriptional "master regulators" from patients. Marcella is supported by a grant from the German Research Foundation (DFG).  Marcella loves to hike and is planning to run the New York marathon in 2026! 

Yana Geng, PhD

Qiuyan Sun (PhD candidate)

Marcella Steffani, MD

Yana obtained her Ph.D. from the University of Groningen, Groningen, the Netherlands. She is interested in exploring novel therapeutic targets in cancer liver metastasis combining human data and mouse models. Yana is a food lover.

Qiuyan Sun (PhD candidate)

Qiuyan Sun (PhD candidate)

Qiuyan Sun (PhD candidate)

Qiuyan received her BS in Nutritional Sciences from Cornell University and joined the Schwabe lab in 2021 for her PhD thesis. She is interested in finding  therapeutic vulnerabilities for  intrahepatic cholangiocarcinoma. Outside lab, she is an amateur writer in science fictions.  She is also the mother of two cats (Luke and Leia).

Dhruv Goyal (undergrad)

Qiuyan Sun (PhD candidate)

Qiuyan Sun (PhD candidate)

Dhruv is currently a second year undergrad in the premed track at Columbia University. Dhruv is interested in both clinical medicine and basic science. After contributing to the zonational quantification in Rspo3 ko mice for our Nature paper, Dhruv is now focusing on developing novel models for Kras-driven cholangiocarcinoma.  Dhruv loves to play tennis and is on the Columbia Club team.

Deqi graudated Medical School in China in 1983, and worked as physician majoring in infectious diseases. After working in the Kandel lab for over a decade, he joined the Schwabe Lab in 2016. Deqi supervises all transgenic mice for projects related to  stellate cell biology and liver carcinogenesis. Deqi loves to cook dumplings - if you ever join our lab, you will see how good they are!
