Mason is also a strong advocate for diversity and ethics in tech.
The Industry Leaders
Data science is driving transformative change across nearly every industry. Here are some of the data scientists leading the charge in applying AI to high-impact, real-world problems:
Meredith Broussard
Meredith Broussard is an associate professor at NYU and the author of "Artificial Unintelligence: How Computers Misunderstand the World." Her research focuses on data journalism and algorithmic bias in machine learning systems. She developed the "Algorithmic Equity Toolkit" to help organizations audit their AI systems for fairness. Broussard is known for communicating complex technical concepts to broad audiences.
Daphne Koller
Daphne Koller is the founder and CEO of insitro, a machine learning-driven drug discovery and development company. Prior to insitro, she was the co-founder of Coursera and a professor at Stanford. Koller specializes in applying probabilistic modeling and machine learning to biomedical data to accelerate the search for new treatments. Her current work focuses on leveraging ML across the entire drug development pipeline.
Ziad Obermeyer
Ziad Obermeyer is the Blue Cross of California Distinguished Professor of Health Policy and Management at UC Berkeley. He works at the intersection of machine learning, medicine, and health policy. His research has uncovered racial bias in healthcare algorithms, leading to changes in how health systems allocate resources. Obermeyer is currently focused on developing machine learning tools to improve clinical decision-making and assess algorithmic fairness.
Danah Boyd
Danah Boyd is a partner researcher at Microsoft Research and founder of the Data & Society Research Institute. Her research focuses on the social implications of data-driven technologies, particularly in the areas of privacy, security, and fairness. She has conducted extensive research on how young people use social media and how data analytics can reinforce social inequities. Boyd is a strong advocate for responsible and ethical data practices.
The Rising Stars
Finally, let‘s celebrate some of the up-and-coming data scientists who are already making waves and poised to shape the future of the field:
Timnit Gebru
Timnit Gebru is the founder and executive director of the Distributed AI Research Institute (DAIR), which aims to mitigate the negative impacts of AI through interdisciplinary research. Previously, she was the co-lead of Google‘s Ethical AI team before her controversial departure. Her research focuses on algorithmic bias, accountability, and transparency in AI systems. Gebru is a leading voice for diversity and inclusion in the tech industry.
Daniel Saunders
