MBL


Akash Srivastava, a student in the Brown-MBL Graduate Program in Biological and Environmental Sciences, successfully defended his Ph.D. dissertation entitled “Transdifferentiation of Liver to Pancreas” on August 18 at Brown University. Srivastava, a student in the Molecular Biology, Cell Biology and Biochemistry Department (MCB) at Brown, conducted his research at the MBL’s Eugene Bell Center for Regenerative Biology and Tissue Engineering under the advisement of MBL Associate Scientist Marko Horb. His doctoral committee members also included Rich Freiman, Kristi Wharton, and Eric Morrow from the MCB Department.

Srivastava’s doctoral research helped to elucidate the molecular mechanisms involved in transdifferentiation of liver to pancreas in the frog Xenopus laevis. He identified a previously unknown role of a highly conserved beta-catenin inhibitor protein (Chibby) in transdifferentiation of liver to pancreas and in normal pancreas development. His research also provided a better understanding of the function of Wnt/beta catenin signaling in pancreas development. Funding for his research came from the Horb lab at with grant support from the National Institutes of Health.

After completing his final manuscripts, Srivastava plans to work as a validation consultant in the pharmaceutical industry.

UChicago Center in Delhi

MBL Marine Resources Manager Dave Remsen and University of Chicago Center in Delhi Executive Director Bharath Visweswariah

Marine Resources Manager Dave Remsen recently visited the University of Chicago Center in Delhi, India while traveling there on other business. UChicago opened the new Center last spring, billing it as an “intellectual destination” offering 17,000 square feet of lecture halls, seminar rooms and offices designed to invite and expand global collaboration across institutions and disciplines. The Center is interested in fostering collaborations within three broad areas of study: Business, Economics, Law, and Policy; Culture, Society, Religion, and the Arts; and Science, Energy, Medicine, and Public Health.

While at the Center, Remsen met with Executive Director Bharath Visweswariah to discuss the new MBL-UChicago affiliation and potential collaborative opportunities between the Delhi Center and the MBL. Stay tuned for more information.

Take a look at the eye-popping, deep-sea exploration footage in this video about the Center for Dark Energy Biosphere Investigations (C-DEBI). Julie Huber, associate director of the MBL’s Bay Paul Center, is also associate director of C-DEBI, a National Science Foundation Science and Technology Center at the University of Southern California.

The researchers involved with this collaborative national center, Huber says, are asking the “big questions” about life in the deep ocean and below the seafloor. “We are at the exponential exploratory phase,” says Huber, who is on the pioneering edge of discovering subterranean microbial life.

Keating-at-OBFS-NML-meeting-9-2014-cropU.S. Representative Bill Keating visited Lillie Auditorium this morning to address members of the Organization of Biological Field Stations (OBFS) and the National Association of Marine Laboratories (NAML), who are holding a joint meeting at the MBL.

Keating remarked on the exponential advances in information technology that allow scientists to transmit data from field stations “instantly, accurately, and efficiently.” He also commended the two groups for collaborating. “Working jointly, with the information you gather, creates enormous opportunities” in the private sector as well as in environmental science, Keating said.

Keating represents the 9th district of Massachusetts, which includes Cape Cod and the islands. He was invited to the MBL by Sarah Oktay, president of OBFS and director of the UMass Boston Nantucket Field Station. MBL Senior Scientist Alan Kuzirian is the founding secretary/treasurer of NAML ( from 1990-2014).

Joe DeGiorgis, assistant professor of biology at Providence College, brought four undergraduates to the MBL last summer to conduct research on the squid–a star model system of neurobiology. The experience was “incredibly enriching,” said one undergraduate. “You can’t do any better than this.” DeGiorgis is also adjunct faculty in the MBL’s Cellular Dynamics Program. Read more here.
