DJ Patil

From graduating near the bottom of his class to becoming the first U.S. Chief Data Scientist, tasked with unleashing the power of data for all Americans. That’s the arc of Dhanurjay “DJ” Patil’s remarkable career. DJ Patil’s life is a testament to the transformative power of data, guided by a relentless pursuit of using complex information to solve some of society’s most pressing problems. He’s tackled everything from anticipating global threats to reforming the justice system and advancing medical research. It’s a compelling narrative of intellectual curiosity and impactful application. Born in 1974, DJ Patil grew up in Cupertino, California, attending Kennedy Middle School, Monta Vista High School, and De Anza College. He even participated in a student exchange program to Toyokawa, Cupertino’s sister city in Japan, in 1988. But his high school years weren't exactly stellar. He often found himself in trouble and, in 1992, graduated near the bottom of his class. His path took a turn at De Anza Community College, where he followed his girlfriend. From there, he found his footing, earning a Bachelor of Arts in mathematics from the University of California, San Diego. His academic journey continued, culminating in a PhD in applied mathematics from the University of Maryland’s College of Computer, Mathematical, and Natural Sciences. While a faculty member there, he even put open datasets from NOAA to use, improving numerical weather forecasting. His career began to take shape in various influential roles. In 2004, he was working in the Advanced Systems and Concepts Office in the Department of Defense. He led the Threat Anticipation Project, using social network analysis to foresee threats related to terrorism, weapons of mass destruction, and failing states, with a particular focus on human rights violations. He described himself as part of “the second wave of people” using data to detect “signaled noise,” a concern that grew acutely after the 9/11 attacks. Patil’s talent for translating complex data into actionable insights became increasingly evident. While a data-scientist-in-residence at Greylock Partners, he authored two influential books: “Building Data Science Teams,” which offered advice on creating effective data science teams in business and technology, and “Data Jujitsu – The Art of Turning Data into Product,” a guide to solving data science problems and determining their true value. His career trajectory accelerated significantly when, on February 18, 2015, the White House announced his appointment as the first U.S. Chief Data Scientist. This was a pivotal moment, and in public addresses, Patil articulated his mission clearly: “The mission of the U.S. Chief Data Scientist, simply put, is to responsibly unleash the power of data to benefit all Americans.” His team’s priority, he added, was to achieve this by creating data. In a memorandum titled “Unleashing the Power of Data to Serve the American People,” Patil outlined his ambitious goals. These included maximizing the social return on federal data, creating nationwide data policies, establishing best practices for data management, and recruiting top data science talent for public service. During his tenure, he championed several groundbreaking initiatives. In response to the Ferguson shootings in 2014, President Obama initiated The President's Task Force on 21st Century Policing, which included Patil’s Police Data Initiative and the Data-Driven Justice Initiative. The Police Data Initiative aimed to build trust between law enforcement and communities by releasing datasets on stops and searches, uses of force, and officer-involved shootings. This transparency, he believed, would increase accountability and allow for the investigation of patterns of injustice. He noted the challenge of disorganized data within police departments, proposing dedicated technicians to standardize data collection across the country’s 18,000 jurisdictions. Over 170 datasets were released at the initiative’s start in 2015. Building on this, the Data-Driven Justice Initiative sought to use open police data to track law enforcement’s disproportionate interactions with minorities, the poor, and those with mental health concerns. Patil envisioned a system where effective data analysis could advance reforms, increase efficiency, and prevent injustice. The initiative aimed to help governments filter low-level offenders and those with mental illness from the criminal justice system, particularly by changing approaches to pre-trial incarceration. At its inception, the DDJ covered over 91 million people. Patil also had a special interest in leveraging data to improve the medical field through the Precision Medicine Initiative (PMI). The PMI sought to build the largest database of genomic information to enhance understanding of cancer treatments, chronic diseases, and rare conditions. He highlighted the need for a diverse dataset to enable comprehensive analyses and correlations, believing it could reveal that some so-called “rare” diseases are actually quite common. A critical aspect of the PMI for Patil was trust. Recognizing the ethical concerns and vulnerabilities involved, he organized workshops and “listening sessions” to address public anxieties. From this feedback, he devised “privacy and trust principles,” with the foremost being that “data access, use, and sharing should be permitted for authorized purposes only.” He even expressed concerns that the American Healthcare Act could deter people from donating genomic information due to fears about exposing pre-existing conditions, despite existing protections like the Genetic Information Nondiscrimination Act. After his time as Chief Data Scientist, Patil continued to apply his expertise. He served on the National Infrastructure Advisory Council and, in October 2017, joined Devoted Health as Head of Technology. He also became an adviser to the American venture capital firm Venrock and, in February 2023, a general partner at GreatPoint Ventures.
