## Texas A&M - Beihang Summer Program

**Time:** 1:15PM - 2:15PM

**Location:** BLOC 220

**Speaker:** Alan Dabney, Texas A&M University - Statistics

**Description:**

**Title:** Genomics and genome-wide statistical hypothesis testing

**Abstract:** Genomic data are high-dimensional, consisting of thousands-to-millions of features. One common application is to apply statistical hypothesis testing to select from the list of features a subset that appear to exhibit differences between comparison groups. For example, if the comparison groups are cancer and normal, we might want to find the subset of genes that are differentially expressed in cancer subjects relative to normal subjects. Classical statistical hypothesis testing was designed for application to one or a few hypothesis tests, and hence the classical Type I error rate and its associated p-value are not ideally applied to genomic data. Instead, an alternative error measure called the False Discovery Rate (FDR) and its associated q-value have become the standard. In this talk, I will present a brief overview of genomics data, FDR and q-values and talk through a differential expression analysis of a small real example RNA-Seq dataset of transcription measurements for 60,000 genes under two conditions.

**Time:** 2:15PM - 3:15PM

**Speaker:** Prof. Igor Zelenko, Texas A&M University

**Description:** **Title:** Optimal Control Problems from geometric viewpoint.

**Abstract:** We will give a brief motivation and formulation of problems in Optimal Control Problem , why Symplectic and Differential Geometry provides the natural framework for qualitative study of them, and conversely how the Optimal Control problems can be useful in study differential geometric properties of underlying geometric structures.

**Time:** 3:30PM - 4:30PM

**Location:** BLOC 220

**Speaker:** Paulo Lima-Filho, Texas A&M University

**Description:**

**Title:** From Euler to Deligne: The Unified Nature of Mathematics

**Abstract:** In this general talk we present a historical bridge from the work of Euler , through the work of Deligne, to recent results in algebraic geometry and equivariant homotopy theory. The historical development of the so-called "regulator maps" keeps a common thread linking number theory, complex analysis, differential and algebraic geometry, and homotopy theory. The talk is accessible to undergraduate students.
