Molly Hayes

Hello! I am Molly Hayes and I serve as the Scholarship Director of Girls in STEM. I have always been passionate about volunteering and helping others, and I am excited for the opportunity to serve young girls through this nonprofit organization. I held many leadership positions throughout college, and I look forward to continuing to influence and encourage others. 

I graduated with a BS in Biomedical Engineering from Baylor University, and I currently work as an engineer for a tissue bank. I have learned so much about writing validations, launching new products, and improving processes. I have also experienced what it is like to be a woman in the workforce. I have faced many challenges as a woman engineer, and I would like to see greater acceptance for women in STEM fields. I am excited to invest my time in such an incredible organization to watch these girls grow into confident young women.

Emily Singer

Hello, I’m Emily Singer! My passion for renewable energy came during high school while watching the destruction taking place during the BP oil spill in the Gulf Coast. I was haunted by the images of wildlife and humans suffering by the drilling of fossil fuels, and from there my desire for researching renewable energy and environmental protection was formed. In college I studied biology, environmental science, and government to get a better understanding of how to best protect our environment while working with our country's governing bodies, fueling my interest in politics and activism. After graduation from Skidmore College with Honors in Biology, I moved to Denver to work at the National Renewable Energy Laboratory, where I research renewable chemicals and energy that could be generated by yeast and bacteria. During this time, I wanted to get involved in organizations that empowered young women, particularly those interested in STEM, which is how I discovered the wonderful organization Girls in STEM. I have been participating in this organization since the Fall of 2016, and it has been an absolute privileged merging my passion for science for my desire to empower young women to be leaders, especially in the STEM field. I am currently working at Gevo, a company making isobutanol from yeast to make renewable fuel and chemicals, and I am exciting to share my learning experiences in labs with young women aspiring to do similar work.
