Probing decision-making processes to understand behavior and find new disease treatments Bernardo Sabatini, the Takeda Professor of Neurobiology at Harvard Medical School, studies how the brain helps animals decide what to do next. This video is part of a series in which scientists explain the importance of their work:

Studying why some genes are activated at inappropriate times in cancer and beyond Stirling Churchman, assistant professor of genetics at Harvard Medical School, studies how the information encoded in DNA is read out by the cell such that genes are turned on at the right time and place. This video is part of a series in which scientists explain the importance of their work:

Revealing causes and consequences to inform policies for a healthy U.S. people and economy Michael Chernew, professor of health care policy at Harvard Medical School, studies the causes and consequences of health care spending growth. He seeks to identify policies and programs that will help the United States maintain both a healthy population and a healthy economy.

Anne Becker, the Maude and Lillian Presley Professor of Global Health and Social Medicine at Harvard Medical School, and her colleagues partner with communities around the world to tackle some of the most vexing problems in global health delivery. She and her research team are developing a school-based intervention in Haiti to link youth with mental illness with support and health services.

Investigating neural circuits in animals to understand how humans process smell When it comes to investigating the brain, there's a surprise at the end of every story, says Bob Datta, assistant professor of neurobiology at Harvard Medical School. This video is part of a series in which scientists explain the importance of their work:

Examining how cells use and produce energy and the role energy balance plays in disease Marcia Haigis, associate professor of cell biology at Harvard Medical School, studies how cells use and produce energy during times of stress. This video is part of a series in which scientists explain the importance of their work:

The timing and sequence of genes turning on and off is key to understanding disease Angela DePace, assistant professor of systems biology at Harvard Medical School, loves little things like labeling her test tubes in addition to tackling big scientific questions. Her lab studies how genes are turned on and off in space and time. This video is part of a series in which researchers explain the importance of their work:

Learning how our sense of smell impacts our behavior and perception of the world Stephen Liberles, assistant professor of cell biology at Harvard Medical School, feels like a detective solving mysteries in the lab. He studies how the brain generates perceptions and behaviors. This video is part of a series in which scientists explain the importance of their work:

Studying the architecture of the brain to gain insight on devastating mental conditions David Van Vactor, professor of cell biology at Harvard Medical School, feels like a detective solving mysteries in the lab. He studies the development of the brain, an intricate and beautiful tapestry made of 100 billion neurons that magically weaves itself during early development. This video is part of a series in which scientists explain the importance of their work:

Gaining insight on why only some tumor cells respond to specific drugs and treatments Galit Lahav, associate professor of systems biology at Harvard Medical School, enjoys the moment when she understands something in a new way, bringing fresh insight to a scientific problem. She uses live-cell imaging to follow the behavior of individual cancer cells.
