Reaching the Moon Thanks to Physics, Theatre, Math, and Dance
The supportive liberal arts community Ben Kolligs BA ’18 found at L&C provided him opportunities to discover his passion in robotics and to advance his career, even before he graduated. Next up, graduate studies in robotics at Carnegie Mellon University!
Linus Brogan ’22 Takes Second in Secure Coding Tournament
On June 19, 2021, the Portland chapter of the Open Web Application Security Project (OWASP), along with chapters from Vancouver, BC and Victoria, BC, hosted the AppSec Pacific Northwest Conference. The conference focused on how to build secure software, defend against attacks, and practice finding potential flaws. Linus Brogan BA ’22 competed in the associated secure coding tournament, finishing in second place. The tournament involved identifying insecure code, analyzing the types of vulnerabilities, and finding the best way to fix the flaws. Brogan is majoring in Computer Science & Mathematics and minoring in Physics.
Krussel Retires After 34 Years
Associate Dean of Student Academic Affairs and Professor of Mathematics John Krussel has retired after 34 years at Lewis & Clark.
First-gen student-athlete is UCLA bound
Jordan Gonzalez BA ’21 is this year’s winner of the Rena J. Ratte Award, Lewis & Clark’s highest academic honor. This fall, Gonzalez will begin a five-year PhD program in chemistry at the University of California at Los Angeles.

National Science Foundation Honors Two Alumni
Two recent Lewis & Clark alumni have been awarded National Science Foundation Graduate Research Fellowships. Three other L&C alumni have been given honorable mentions.
New Data Science Minor Builds from Interdisciplinary Foundation
Through strong critical thinking and problem-solving skills, data science engages individuals in computing, statistics, interpretation, and communication. The new minor will reflect the strength of a liberal arts curriculum above all else, thanks to the diligence and passion of faculty members across the college.
Computer Science’s New Concentration: Cybersecurity
Starting in the fall of 2021, Lewis & Clark’s Department of Mathematical Sciences will begin offering a new concentration within the computer science program: cybersecurity. The new concentration in cybersecurity provides students an interdisciplinary approach, bringing together technology, people, information, and processes through the creation, operation, analysis, and testing of secure computer systems.
Mathematics and Chemistry Double Major Named Rhodes Finalist
Jordan Gonzalez BA ’21 advanced to the final round of interviews for the Rhodes Scholarship, widely regarded as the most prestigious international scholarship program in the world. The scholarship allows exceptional, leadership-driven students from around the world to pursue higher degrees at the University of Oxford. Gonzalez is the fourth Lewis & Clark student to be named a Rhodes finalist in the last five years.

Title: Modeling the Effect of Quorum-Sensing Regulated T6SS-Mediated Killing on Biofilms
Abstract: Bacterial interactions heavily impact how a biofilm forms, and how bacteria communicate impacts how they interact. One way that bacteria can communicate is through the production and sensing of quorum sensing molecules which regulate certain genetic expressions. It was our focus to model and analyze the relationship between quorum sensing regulated Type VI Secretion System (T6SS) mediated killing in two strains of Agrobacterium tumefaciens and biofilm structure. We constructed a deterministic two dimensional model that held the rate of quorum sensing molecule production constant in order to illustrate basic interactions between two bacterial strains and the effect that such interactions have on the biofilm’s development. By adding another dimension to our model we can more realistically show the effects that quorum sensing regulated T6SS mediated killing has on the biofilm’s structure based on the current state of the biofilm. This work illustrates how quorum sensing T6SS mediated killing contributes to overall biofilm structure.

Title: Numerical Analysis of the 1-Dimensional Parabolic Optimal Transport Problem
Abstract: Numerical methods for the optimal transport problem is an active area of research. Recent work of Kitagawa and Abedin shows that the solution of a time-dependent equation converges exponentially fast, as time goes to infinity, to the solution of the optimal transport problem. This suggests a fast numerical algorithm for computing optimal maps; we investigate such an algorithm here in the 1-dimensional case. Specifically, we use a finite-difference scheme to solve the time-dependent optimal transport problem and carry out an error analysis of the scheme. A collection of numerical examples is also presented and discussed.

Tuesday, February 15, 202210:30-11:30Title: Application of Machine Learning and Deep Learning Neural Networks in Health Informatics Abstract: With the rapid development in technology, more and more data are available for data analysis tasks. To glean useful insights from diverse data sets and develop predictive models, machine learning (ML), including deep learning (DL) methods, become the most promising solutions. Health Informatics have been vital research areas where ML and DL hold great promise in improving healthcare. In the research presentation, I include multiple studies that introduce ML and DL applications in healthcarehttps://zoom.us/j/9016798003?pwd=Kys3OS9FT3ZudkZWYjlXejlzNjVwdz09

Research Talk: Visualization in the Age of Data: Human-looped Science & Design
Abstract: Data is everywhere, but without a means to understand it, data is fundamentally useless. One avenue to make data meaningful is the use of visualization—interactive computer graphics for visually analyzing information. But while visualization has attended to data sets of ever increasing size, we cannot lose track of the very human nature of visualization: It solves problems humans have, so we must use the science of visualization to help those users. In this talk, I discuss a few examples of how we have used visualization to address important problems while keeping the user in the loop. These designs incorporate expert analysis, user studies, and more. I conclude with some thoughts on future directions of visualization research.

Research Talk: Low Rank and Sparse Methods for Data Science
Abstract:
In order to better understand large data-sets, it is helpful to understand the underlying patterns. Even when the underlying pattern is nonlinear, the data matrix can be approximated as being low rank, a property that allows for techniques to analyze the data in terms of a low dimensional latent space using Principal Component Analysis (PCA) or non-negative matrix factorization (NMF), identifying outliers through Robust PCA, and accurately inferring missing entries from very few observations of a matrix through matrix completion.
