Welcome to the Tang Lab!
My lab employs metabolic modeling, systems "omics" analyses, and genetic engineering to investigate and modify cell metabolism under diverse growth conditions. The metabolic modeling/analysis tools can understand cell metabolisms and identify rate-limiting steps. Combining "omics" with metabolic engineering will provide an iterative route to develop microbial cell factories (design-build-analysis-learn loop). On the other hand, discovery and development of new platform strains using nonmodel microbes is a promising direction so that we can take advantage of native pathways in platform strains for biosynthesis. Therefore, my Lab often works on "hypothesis-free" researches with environmental microbiologists for characterizing novel microbial metabolisms. On the other hand, the microbial metabolism has been optimized through many years of natural evolution. Loading of Synthetic Biology parts may drain cell resources and disrupt cellular functions. When the host cannot afford these burdens, undesirable physiological responses will take place - removal of one bottleneck in the parent strain breeds new problems in the daughter strain. Therefore, synthetic biology strains are difficult to achieve the desired performance. To overcome these problems, we use flux analysis and data driven models (such as machine learning) to predict outcomes from synthetic biology designs (What is possible? What is deliverable?).
My lab is supported by two grants: DoE BER Rhodococcus project
(Co-PI, 2017~2020); NSF MCB project on machine learning for microbial cell
factories (PI, 2016~2019). My lab also receives small amount of money from
industries. Currently, we are helping Arch Innotek develop nonmodel yeasts for
aroma and drug productions via NSF/NIH small business grants.

I teach process control (EECE401) and bioprocess engineering (EECE506). Both courses cover significant amount of computer modeling and data analysis. As an undergraduate director, I enjoy teaching very much. I have open door policy and students can stop by for questions at any time. Moreover, I have mentored over 50 UG/high school students for their summer research in my lab via NSF REU and MAGEEP programs. My lab also supports WashU iGEM teams. Each year, my lab hosts a few MS students for independent studies.
PhD students in the Tang Lab need to learn both lab skills and computer modeling. Moreover, PhD students often do internship to accumulate industrial experience (e.g., Mary for BASF, Gang for Sigma, Whitney for LBL, Lian for Sandia National Lab, Tola for Monsanto, and Jeff for Arch-Innotek). PhD students usually published 7~8 papers from their research. They also have 2~3 trips to AICHE or SIMB conferences during their PhD studies. So far, Seven PhD students have graduated. After graduation, most of students work for industry or academia except Whitney (she currently works as a program manager in US EPA in Washington DC). The first two PhD students landed faculty jobs (as tenure track assistant professors): Xueyang at Virginia Tech and Arul at Arizona State University. Recent graduates obtained industrial or government jobs without postdoc training (Whitney works for US EPA, Gang works for Sigma-Aldrich; both Ni works for Monsanto).
Trained as a chemical engineer, PI Tang's research fields cover both synthetic biology and bioprocesses. His diverse background prepares him well as a reviewer for proposals (panelist for NSF, EPA and DOE) and papers (including ACS SynBio, Bioinformatics, MEng, Nature Comm, Nature Biotech, Plos Comp Bio, Science, Scientific Report). His other national services are associate editors for three biotechnology journals.
