Ironically, Dan’s undergraduate degree and brief career in neuroscience inspired him to write about research rather than conduct it, culminating in him earning a master’s degree in science journalism from New York University in 2017. In 2018, an Undark feature Dan and colleagues began at NYU on a questionable drug approval decision at the FDA won first place in the student category of the Association of Health Care Journalists' Awards for Excellence in Health Care Journalism. Now, Dan writes and edits stories on all aspects of the life sciences for the online news desk, and he oversees the “The Literature” and “Modus Operandi” sections of the monthly TS Digest and quarterly print magazine.
