Francisco Javier Quintero Cortes

“Success is stumbling from failure to failure with no loss of enthusiasm.” - Winston Churchill

After obtaining his Bachelor’s and Master’s degrees in Chemical Engineering at the National University of Colombia, he was awarded a Fulbright scholarship to pursue a PhD in Materials Science and Engineering at Georgia Tech. He graduated in 2020 and started his own energy storage company, Capacitor Foundry. Outside the lab, Francisco won second place in the 3-minute thesis competition in 2018, and first place in the Teams for Tech pitch competition for GradChats, a student-led mental health initiative for graduate students. He also served as president of the Fulbright Student Association, outreach officer in Grad Pride, Graduate Vice President of Professional Development at the Student Government Association.

What inspired you to become a Leadership Fellow?: Francisco is a coach to learn from other leaders. For him, leadership is more about cultivating relationships and growing personally than about achieving any specific goals. In his experience, personal goals are always exceeded when different views, passions, and skills are put together. His experience has also shown that there are many elements that can lead to chaos and failure when working with others. Having/being a coach is a great way to recover enthusiasm in the middle of the chaos and in between failures.

What inspired you to become a Leadership Fellow?: Samantha believes coaching is one of the most meaningful and intentional skills you can develop as an individual in order to support the development of others. As she continues to grow into leadership positions both personally and professionally, she sees becoming a coach as developing a new way of communicating and thinking so that she may learn to listen differently and therefore be able to empathize while also asking the challenging questions; empowering others in their own strengths to tackle whatever is ahead. Samantha’s mother has always been a powerful influence in her life and one lesson of the many lessons she learned from her mother was that she will often be her own harshest critic and that failure is part of the process of growing. This advice has allowed Samantha to balance her heart and her head when processing a decision or responding to a situation.
