Entering college, Laura Bright was drawn to both French and math, two subjects she exceled in in high school. French remained something that came easily and she took for fun. But the math she took in college didn’t look like high school math and she wondered if that was the right path. As the department was combined with computer science, she took the advice of a female researcher and tried her hand at computer science.

She was drawn the more technical sides of her field but never considered herself a programmer. She thought she wanted to teach and make computer science come alive for other learners so pursued the PhD. She realized, though, that she wanted more hands on opportunities. Going into industry, she did more applied work and ultimately made a discovery about herself.

In this episode, find out from Laura how taking the opportunity just outside your comfort zone often leads to insights about who you are… on ROADS TAKEN...with Leslie Jennings Rowley.

This EP is an interview with Carlos Balsalobre-Fernandez a professor of sports science teaching biomechanics and sports technology at the Autonomous University of Madrid. He is also a self-taught iOS developer of MyJumpApp which is a unique application that allows you to video various jump tests and derive important data points for performance analysis. He often speaks around the world at performance events and workshops about performance monitoring, strength testing, and technology implications in performance.  He’s also a researcher and author of 40+ peer-reviewed scientific publications. I met him several years ago at an event hosted by David Martin of the Philadelphia 76ers and loved hearing about the work he was doing.  We get into his APP development and much more in the amazing conversation, enjoy!  BTW, the next cohort of the LYM Life Lab begins in October 2022 - grab your LYM Life Lab starter kit FREE here https://lymlab.com/free-lym-lab-starter/ or apply today at https://lymlab.com/lym-lab/

Ella Ehrlich has been a developer at Jane Street for close to a decade. During much of that time, she’s worked on Gord, one of Jane Street’s oldest and most critical systems, which is responsible for normalizing and distributing the firm’s trading data. Ella and Ron talk about how to grow and modernize a legacy system without compromising uptime, why game developers are the “musicians of software,” and some of the work Jane Street has done to try to hire a more diverse set of software engineers.

You can find the transcript for this episode  on our website.

Some links to topics that came up in the discussion:

• EG, The League of Legends team that Ella is a huge fan of.
• Apache Kafka, the message bus that Gord migrated to.
• Some of the various sources of symbology you have to deal with when normalizing trading data. (Really, there are too many sources to list here!)
• A list of Jane Street’s recruiting Programs and Events, including INSIGHT, which focuses on women, and IN FOCUS, which focuses on historically underrepresented ethnic or racial minorities.

He then completed residency training in Family Medicine and a fellowship in Sports Medicine. He is board-certified in both Family Medicine and Sports Medicine, and his practice focuses on the non-surgical management of sports injuries, as well as athlete training, health, rehabilitation, and wellness. He completed his Ph.D. (exercise physiology) in the Jones Laboratory at the University of Exeter (UK), where his research studies focused on oxygen kinetics, the determinants of athlete power production, athlete performance, and their relationship to training. Dr. Skiba is the Program Director of sports medicine fellowship at Advocate Lutheran General Hospital, in Chicagoland, and is the Regional Director of Sports Medicine for the AdvocateAurora Medical Group, one of the largest in the United States. He is also a team physician for the University of Illinois (Chicago).

Dr. Skiba has been working in sports training and performance for more than 2 decades. As a sports physician, he works clinically, on the sidelines, and in the training room with high school, NCAA Division 1, and professional athletes. He has trained a number of Olympian and World Champion endurance athletes and is a regular face in broadcast journalism. Most recently, Dr. Skiba was a consultant on the Nike Breaking 2 project, where he traveled 3 continents training the best marathon runners in the world, appearing in the Cannes Film Festival award-winning documentary Breaking 2.

In this episode of the KoopCast Coach Jason Koop speaks with Shawn Arent. Performance tests are abundant now a days and can range from blood monitoring services like Inside Tracker to FatMax testing and VO2max testing. But how do you make sense of it all and which tests are valuable for athletes? 

Shawn M. Arent, PhD, CSCS*D, FISSN, FACSM is Professor and Chair of the Department of Exercise Science at the University of South Carolina, which is currently the top-ranked program in the United States. He is also the Director of the UofSC Sport Science Lab. Prior to this, he was the Director of the Rutgers Center for Health & Human Performance. His research focuses on the relationship between physical activity and stress and the implications for health, performance, and recovery. Dr. Arent’s recent work has primarily focused on physiological responses to training-related stressors and their contribution to optimal performance and recovery. He was named the 2017 William J. Kraemer Outstanding Sports Scientist of the Year by NSCA. He is a fellow in ACSM and ISSN and is the current President of ISSN. Additionally, he has worked with teams in the NHL, MLB, the US Soccer Federation, and a number of teams at the youth, high school, and collegiate levels.
