Aylin D.

Aylin is a graduate of University of California Santa Cruz where she earned her B.S. in Computer Science and Computer Game Design at the Jack Baskin School of Engineering. Aylin is a game developer and designer and an all around video game enthusiast—which is ideal for teaching Scratch. After working with students in User Research-based settings, Aylin found a passion for teaching when she saw how her students, specifically young girls, became inspired to explore technology by seeing how involved and enthusiastic she was about game development. Reflecting on her own educational upbringing, she recognized the importance of having role models (such as her mother, an intelligent systems engineer) who inspired her to pursue a career in technology, despite the odds and lack of representation. Aylin hopes to similarly inspire her students to explore STEAM subjects and careers and guide them through any difficulties that may arise. Aylin also continues explore and develop games that serve a purpose other than entertainment, i.e. games that hold the potential to help someone in their daily life, physical or mental health. She hopes to use her interests to teach students about such games so that maybe one day they can create them as well.


Raquel S. 

Raquel received her BA in Psychology from the University of Illinois-Chicago and her MA in Developmental Psychology from San Francisco State University, where she conducted research on learning and behavior in preschool age children. At Duke University, Raquel was part of a behavioral economics research group that explored financial literacy among families with young children and identified useful tools for financial education. At Stanford, Raquel was involved with the Sightlines Project at the Center on Longevity, which investigated how financial security, healthy behaviors, and social engagement can lead to longevity (living well to the age of 100 and beyond).  

In addition to her research, Raquel has extensive experience teaching students of all ages in a variety of settings. Early in her career, Raquel developed math curriculum for students (grades 9-12) with learning disabilities at Yeshiva University High School in NYC, as well as being an SAT instructor for the Princeton Review. Raquel has also taught the undergraduate level Intro to Statistics course at SF State University, where she was also a Lab Instructor and TA in the Dept. of Psychology. Raquel has also been an active Volunteer Teacher in the Palo Alto Unified school district, helping K-5 students with Math coursework.

Karen has a B.S. degree from Stanford University in Management Science and Engineering with a focus in Organizations, Technology, and Entrepreneurship. Before joining the Starfire team, she worked as a product manager for mobile applications at a technology company in Silicon Valley. Growing up, Karen was both an avid babysitter and tutor and she loves the opportunity to share her passion for STEAM with kids of all ages through Starfire's after school programs. Outside the office, Karen loves to read philosophy and psychology books, travel the world, play soccer, and pet as many dogs as possible.


Joe C.

Joe graduated from Princeton University with a B.A. in Philosophy, and is an acquisition editor for an academic publisher of graduate-level e-books. Joe works with authors and editors to produce educational resources for researchers at the cutting edge of neuroscience, cell biology, physiology, and experimental biomedicine. Previously, Joe worked at the American Association for Cancer Research, promoting and supporting preclinical and translational cancer research programs for its 30K plus members worldwide. Joe is passionate about training the next generation of scientists and implementing innovation in education. Joe was on the Varsity Fencing team at Princeton and volunteers for SoccerFours, an adult pick-up soccer league in San Francisco.


Nathan H.

Nathan Hechtman is a Palo Alto native. He went to Ohlone Elementary, Jordan (now Greene) Middle School, and finally Palo Alto High School before studying Biology at Willamette University in Oregon. He has been teaching and mentoring youth for nearly a decade, including working at summer camps in high school, teaching high-schoolers about biology during college, and tutoring during and after college.

Nathan loves to tailor math to students' interests. A child who cannot stop talking about sports may calculate baseball statistics. A student fascinated by programming might explore basic linear algebra. An avid player of board games can investigate the math behind good strategies. Whatever excites a student, they are encouraged to pursue it mathematically.


Laura D.

M.S.E., Computer Engineering, Control Theory, Santa Clara University
M.B.A., General Management, UC Berkeley and Columbia University
B.S.M.E., Biomedical Mechanical Engineering, Washington University, St. Louis

Laura is an educator, executive consultant, entrepreneur, and judge for STEM competitions. Laura taught students in 10th through 12th grade in Computer Science at The Bay School of San Francisco for the 2017-2018 school year. In past roles, she has led technology teams in cleantech, software and biotech for 10+ years across multiple functional areas and industries, focused in renewable energy and energy efficiency for 5+ years.

Laura is passionate about all sides of the STEM field. In parallel to her tech roles, she has taught UC Berkeley, secondary, and elementary school computer science for 10 years; tutored math, and has been an advisor to several STEM startups. Laura is also a judge for high school, college, and government funded (DOE solar) grants and competitions in STEM. While teaching at UC Berkeley Extension, Laura developed the UC Berkeley curriculum for Microsoft Windows programming development and published the textbook Windows Programming Under the Hood of MFC, based on her applied approach to teaching students how to develop object-oriented software.


Jennifer Y.

Upon graduation with her M.S. in Computer Science from New York University, Jennifer worked at a variety startup companies in Silicon Valley. Her deep passion for software development led her through the early days of database internal R&D to internet infrastructure systems. In addition, she has broad engineering and project/program management background, and experience working with large development teams and managing cross-continent software releases.

From 2007 to 2013, Jennifer traveled across the continent, meeting with many exceptional teenagers and their families. She gained valuable insights on how to raise a child: proper empowerment, support, and inspiration are all important to the development of every child. An adaptive and open learning environment is essential, and there is no black/white rule.

Jennifer has been teaching college level Computer Science and database courses since fall 2015. She introduced various Computer Science concepts and basic programming in Python and SQL to adult students coming from diverse ethnic and cultural backgrounds. As a teacher for Starfire Education, Jennifer spent the past few years teaching middle school students the Python programming language, Design Thinking, and general applications of Computer Science concepts.

Jennifer loves constructing contemporary structures and enjoys listening to the music of Johann Sebastian Bach.



Aparna has a Graduate degree in Physics (Electronics) with a Post Graduate degree (M.Phil.) in Physics (first rank holder in her batch) from IIT Roorkee, India. She did her pre-doctoral thesis on measuring the size of atmospheric particles. She is a proud mother of a daughter and a son. She taught her kids through their high school studies, and she loves teaching math and science to elementary school kids because this is their age of foundation. Her philosophy is that kids are very creative and they don’t want to stick to one way to solve a problem, but rather, can find solutions to a problem in different ways through trial and error. She became a Starfire teacher because the Starfire philosophy encourages creativity and connects math and science with real life problems. Her hobbies are trying different recipes in the kitchen and painting.
