TITLE: "Oncogenic alterations in the p53 pathway abolish oscillatory competence" ABSTRACT: The tumor suppressor p53 displays concentration oscillations in response to DNA damage, a behavior that has been suggested to be essential to its anti-cancer function.  Many genetic alterations in the p53 pathway have been shown to be oncogenic, whether by experiment or by clinical associations […]

TITLE: Structural interrogation of small open reading frame (sORF) encoded proteins ABSTRACT: Advances in genomics and proteomics have unearthed sequences of a startling number of novel proteins. Despite this, our knowledge of their three-dimensional structure and function relies on only a small fraction of the known protein universe.  Small open reading frames (sORFs) encoding proteins less […]

TITLE: Cis-regulatory divergence between highland and lowland deer mice populations highlight the essential role of pleiotropic genes for high-altitude adaptation. ABSTRACT: Variation in gene expression regulation contributes extensively to phenotypic diversity within and between species and plays a major role in complex trait evolution. However, the characterization of the genetic basis of regulatory variation is […]

TITLE: "scPNMF: sparse gene encoding of single cells to facilitate gene selection for targeted gene profiling." ABSTRACT: Single-cell RNA sequencing (scRNA-seq) captures whole transcriptome information of individual cells. While scRNA-seq measures thousands of genes, researchers are often interested in only dozens to hundreds of genes for a closer study. Then a question is how to […]

TITLE: "A state space model to characterize the phenotypic variation in a panel of drug treatment time course experiments." ABSTRACT: As new technologies enable high throughput collection of marker measurements in drug treatment time course experiments, we are faced with a need to characterize the observed cellular behaviors over time.  I will present a model […]

TITLE: The evolution and co-evolution of PRDM9 across vertebrates ABSTRACT: In sexually reproducing organisms, meiotic recombination is initiated by the deliberate infliction of numerous double-strand breaks (DSBs) in the genome, the repair of which yields crossover and non-crossover resolutions. In most mammals, these DSBs are specified through the binding of PRDM9 and the deposition of […]

TITLE: "Linking exposure dose to infectious disease development using mechanistic models" (using SARS-CoV-2 in a mouse model as an illustration) ABSTRACT: Disease development after exposure to a pathogen does not follow a yes/no process, but rather a spectrum of disease manifestations influenced by host, pathogen and environmental factors. In particular, exposure dose can impact incubation time, […]

TITLE: “Inferring positive selection in the human gut microbiome using signatures of genetic linkage.” ABSTRACT: The human gut microbiome is composed of hundreds of simultaneously evolving species that can affect human health. However, fundamental features of genetic diversity have yet to be leveraged to identify genes that contribute towards microbial adaptation. One such feature is the […]
