Matthew Blake, BA


My name is Matthew Blake and I was born and raised around Seattle, WA. I graduated with my Bachelors degree in Biology, and soon I will complete my master's degree in Data Science with the hope of continuing a long-term career in bioinformatics. My hobbies include museum hopping, hiking, volunteering, reading, and cooking. I look forward to working and growing alongside my colleagues at WashU and The DRIVES Project.
