Dr. Zeping Hu obtained his Bachelor of Medicine from Shandong University in 2000 and M.S. from the National Institutes for Food and Drug Control in 2003. After that, he pursued his Ph.D. in the Department of Pharmacy at National University of Singapore (2003-2009). From 2010 to 2012, he worked as a postdoctoral fellow with Dr. Richard D.

In 2012, he joined the University of Texas, Southwestern Medical Center as an Assistant Professor (research track). In 2016, he started his independent research as a tenure-track Assistant Professor in the School of Pharmaceutical Sciences, Tsinghua University.

His research interests mainly focus on metabolic analysis, molecular metabolic mechanisms and therapeutic targets of diseases, and pharmacometabolomics-enabled precision medicine. Specifically, his group aims to develop cutting-edge mass spectrometry-based techniques for metabolic analysis, and use these tools to understand the molecular metabolic mechanisms of diseases, to identify and design new treatments to facilitate drug R&D, and to enable precision medicine with optimal efficacy and toxicity. So far, he has published over 30 peer-reviewed papers on the leading journals such as Science, Nature, Cell Reports, Nature Genetics, Cell Metabolism, Journal of Proteome Research, Pharmaceutical Research, Toxicology and Applied Pharmacology, and Journal of Pharmacology and Experimental Therapeutics.

Metabolism is the fundament of physiology, and it has become increasingly apparent that many human diseases such as cancer and diabetes involve the perturbation of metabolism. Metabolomics is a relatively new field of systems biology that detects and quantifies metabolites and analyzes the activity of metabolic pathways. It is emerging to be a powerful technology in both biomedical and pharmaceutical research.

Overall, our goals are to identify the metabolic disturbances in diseases using a variety of precise metabolic analytical techniques, understand the underlying molecular mechanisms, and design optimal therapeutic strategies. To achieve these, we aims 1) to develop cutting-edge mass spectrometry-based techniques for metabolic analysis, and use these tools 2) to elucidate the metabolic mechanisms of diseases and related drug responses (efficacy and toxicity); 3) to facilitate pharmaceutical research & development, such as the identification of novel therapeutic targets, and drug metabolism & pharmacokinetics and toxicity study of new drugs; 4) to develop new diagnostic and/or prognostic methods for monitoring disease pathogenesis/progression; and 5) to stratify patients by pharmacometabolomics phenotyping for enabling precision medicine to achieve optimal drug efficacy and toxicity.

Dr. Hu's research has been focusing on metabolomics and pharmaceutical sciences over the past decade. He has developed a variety of metabolomics and metabolic flux analysis method. Among these, he developed an ultra-sensitive targeted metabolomics method that can detect more than 50-60 metabolites from only a few thousand cells, which makes the metabolomics study possible in extremely rare cells (i.e., hematopoietic stem cells). In addition, Dr. Hu has applied these metabolic analysis methods in several collaborative studies on various diseases. In the collaboration with GlaxoSmithKline, he has accomplished the first metabolomics study in Alzheimer's disease (AD) TASTPM transgenic mice model. This study could help to understand the metabolic mechanisms of the disease, to achieve accurate and early diagnosis, and to evaluate the efficacy of new drug candidates for AD to accelerate the drug discovery process. In addition, Dr. Hu has applied the metabolic analytical methods to a number of basic and translational collaborative studies (including cancer, immunology, and microbiology etc.) and played a key role in achieving the final discoveries. These include the identification of a new metabolic pathway in cancer cells, and the role of metabolism in the pathogenesis or metastasis of lung cancer and melanoma etc. These discoveries may provide the fundaments for understanding the mechanisms of pathogenesis or metastasis and identifying the novel therapeutic targets of these diseases. In the field of pharmaceutical research, Dr. Hu has investigated the effects and underlying mechanisms of co-administered St. John's wort or thalidomide (thalidomide) on the pharmacokinetics, drug metabolism, transport, and toxicity of CPT-11 (irinotecan). These studies could help to understand the effects of drug-drug interactions on the metabolism and toxicity of anticancer drugs, and the discovery of new anti-toxicity approaches. Meanwhile, Dr. Hu has completed the first preclinical pharmacokinetics study of recombinant human parathyroid hormone 1-34 in animals.

2) We have applied the developed techniques to explore the metabolic perturbation in a number of diseases/pathologies, particularly cancer. These include the identification of new metabolic mechanisms in cancer cells, and the role of metabolism in the pathogenesis or metastasis of lung cancer and melanoma.

3) We have investigated the effects and underlying mechanisms of coadministered St. John's wort or thalidomide (thalidomide) on the pharmacokinetics, drug metabolism, transport, and toxicity of CPT-11 (irinotecan).
