Abstracts
February 3, Yunus Tuncbilek: I will talk about value investing and why, in many ways, mathematicians are better suited to be value investors than the general public or even the institutional investors. The talk should be informative and enjoyable for any person who wants to increase their income over a long period of time without doing much work.
February 10, Yingda Li: In this talk, I will begin with a brief intro of my background, followed by a discussion of my journey to my current role as a Research Scientist/Machine Learning Engineer in industry. Finally, I will illustrate the day-to-day duties of a RS/MLE at Meta.
February 17, Rebecca Gasper: There are so many careers in mathematics! Rebecca Gasper (Ph.D. Applied Mathematical and Computational Sciences, University of Iowa) decided to be a math professor by the end of her first calculus class. From tutoring through college and graduate school, preparation and luck, things fell into place. So what changed? She talks about her personal experience first in academia and then in corporate America, from pure math to data science, and gracefully changing her path. Plenty of time will be reserved for Q&A, so bring your questions about getting hired, workload, and culture in each “world.”
February 24, Alisha Zachariah: Any choice of career path comes with its own set of tradeoffs. In my current role as a data scientist at Amazon, my team identifies which products Amazon Retail should carry on the basis of their long-term profitability, in the US and worldwide. In this presentation, I would like to talk candidly about the pros and cons of this professional path, from compensation to #techlayoffs and everything in between.
March 3, Niudun Wang: Having to make a call could be stressful, especially when there's seemingly endless choices and the stake is high. I will be offering from my perspective the pitfalls and hinder sights as a puzzled graduate student that you might find relatable. El Psy Kongroo.
March 10, Kristina Wheatman: Do you ever feel like all your major life decisions keep you running in circles? In Happy Accidents, I discuss ideas for how to maneuver through the chaos and confusion of “grey” crossroads and unpleasant detours within mathematics and academia, especially when “black” and “white” options seem out of reach or prove to be disappointing. I share how I am able to build my own customized career in research by allowing myself some grace and flexibility. Ultimately, I am continuously finding ways to improve my life’s heuristic by acknowledging the “perfect optimal” exists solely to motivate us on our mathematical journey.
