Keynote Speaker

Stephen B. Baylin is currently Deputy Director, Professor of Oncology and Medicine, Chief of the Cancer Biology Division and Director for Research, of The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins.For the last 20 years, Stephen Baylin has studied the role of epigenetic gene silencing in the initiation and progression of human cancer. He and his colleagues have fostered the concept that DNA hypermethylation of gene promoters, and associated transcriptional silencing, can serve as an alternative to mutations for producing loss of tumor suppressor gene function. They have described some of the classic genes involved, invented approaches to randomly screen the cancer genome for such genes and to demonstrate their functional role in cancer progression, helped begin unravel the molecular mechanisms responsible for the initiation and maintenance of the gene silencing, and worked to utilize all of their findings for translational purposes.  Baylin has authored or co-authored over 375 full-length publications on the above and other areas of cancer biology.

Gerecht wins NSF CAREER Award for work in blood vessel formation

Sharon Gerecht (Photo:Will Kirk/JHU)

Sharon Gerecht, assistant professor in Chemical and Biomolecular Engineering at Johns Hopkins University, has been awarded the Faculty Early Career Development (CAREER) Award from the National Science Foundation. The $450,000 prize over five years will help Gerecht in her investigation into how hypoxia, or decreased oxygen, affects the development of blood vessels.

Gerecht’s interdisciplinary research brings together her expertise in stem cell and vascular biology with her background in engineering.  Gerecht said she hopes to discover the mechanisms and pathways involved in the formation of vascular networks, as they relate to embryonic development and diseases such as cancer.

Many medical conditions, such as cancer and heart disease, create areas of decreased oxygen or hypoxia in the spaces between cells. But oxygen is required to maintain normal tissue function by blood vessel networks, which bring nutrients to cells. Likewise, the differentiation of stem cells into more complex organs and structures needs a plentiful supply of oxygen from the vasculature to function.

Gerecht’s study will examine how low oxygen levels impact the growth factors responsible for promoting vascular networks. She also will study the growth of vascular networks in engineered hydrogels that mimic the physical attributes of the extracellular matrix, which is the framework upon which cells divide and grow. Finally, her laboratory will focus on discovering how stem cells differentiate to blood vessel cells and assemble into networks under hypoxic conditions.

She will conduct her research through her role as a project director at the Johns Hopkins Engineering in Oncology Center (EOC), a Physical Science-Oncology Center of the National Cancer Institute. Gerecht is also an associated faculty member of the Johns Hopkins Institute for NanoBioTechnology, which administers the EOC.

Gerecht earned her doctoral degree from Technion – Israel Institute of Technology followed by postdoctoral training at Massachusetts Institute of Technology. She joined the faculty of the Whiting School of Engineering at Johns Hopkins in 2007.

The prestigious CAREER award, given to faculty members at the beginning of their academic careers, is one of NSF’s most competitive awards and emphasizes high-quality research and novel education initiatives. It provides funding so that young investigators have the opportunity to focus more intently on furthering their research careers.

One of Johns Hopkins Institute for NanoBioTechnology’s 2010 summer research interns –Obafemi Ifelowo, a senior molecular biology, biochemistry and bioinformatics major at Towson University– was featured in a recent issue of the Johns Hopkins School of Medicine Science Newsletter. Ifelowo worked in the biomedical engineering laboratory of affiliated faculty member Jordan Green. Read more.

INBT’s summer nanobio internship is a Research Experience for Undergraduates (REU) program funded by the National Science Foundation. The Institute supported 16 students during the summer of 2010 for 10 weeks of research in laboratories across The Johns Hopkins University campuses.  Learn more about INBT’s summer nanobio REU program  here.

INBT’s REU gives students 10 weeks to find out if research is for them

Johns Hopkins University was founded as a research university. But the fact is, research is not the best career path for everyone. That’s why Johns Hopkins Institute for NanoBioTechnology offers a 10-week summer research internship for undergraduate students. There’s no better way to find out if research is for you than to actually do it.

During the summer of 2010, 16 students from universities across the country were admitted into INBT’s highly competitive Research Experience for Undergraduates (REU) funded by the National Science Foundation. This was the third year of INBT’s REU program, and this group of scholars represented the Institute’s largest since the program began. Students are mentored by faculty members, graduate students and postdoctoral fellows in INBT affiliated laboratories across Hopkins.

Projects are designed in such a way that students are able to gather relevant data in such a short period of time. At the end of the 10-week research program, they presented their findings at a university-wide collaborative research poster session held with other summer interns from across several divisions at Johns Hopkins. Some students are invited stay on for a few weeks after the conclusion of their program and continue to work in their assigned laboratories. Several REU scholars have been able to subsequently publish peer-reviewed scientific reports with their advisors.

In addition to their academic and research activities, INBT REU participants have the opportunity to live with other summer interns and mingle at organized and impromptu social events. Outings have included cookouts, crab feasts and Orioles baseball games.

The scene was a sea of white tents spread across the National Mall in Washington, DC and science and engineering were the order of the day. That’s what greeted visitors to the booth hosted by Johns Hopkins Institute for NanoBioTechnology at the first USA Science & Engineering Festival Expo, held October 23-24.

An estimated 500,000 people attended the two-day event, which featured 550 participating organizations and 1,500 hands-on activities. Those who stopped by INBT’s “Nano-Magic” booth learned about how atoms, molecules and materials have ways of building structures all by themselves.

Twelve graduate students affiliated with INBT training programs and a handful of friends of the Institute volunteered to help visitors understand the science. In addition, several of the research and news videos created by INBT’s Animation Studio were on display throughout the day.

An estimated 500 to 600 people came to the INBT booth and spent from 5 to 20 minutes discussing nanotechnology, Johns Hopkins research, and INBT’s training programs. This first-ever event was a major outreach opportunity for INBT and one of the first times the Institute has had a public display of this kind.

(Photo: Mary Spiro)“Outreach serves an important purpose,” said Denis Wirtz, INBT’s associate director and professor of chemical and biomolecular engineering who came out Saturday to assist with the demonstration. “It showcases the interdisciplinary nature of INBT’s work to a broad audience. But it also gives the students an opportunity to explain their research in an accessible way. These outreach activities are a requirement of their training program grants, but this skill will also help them in their future careers when explaining their work to funding sources.”

USA Science and Engineering Festival organizers have not announced whether or not they will host another event like this one next year. INBT leaders indicate, however, that they will be interested in participating in this or similar events in the future.

Six exhibitors from Johns Hopkins presented at the USA Science and Engineering Festival. Along with INBT, they included representatives from the Institute for Data Intensive Engineering and Science and the department of Chemical and Biomolecular Engineering from the Whiting School of Engineering and the undergraduate program in neuroscience, the department of Physics and Astronomy, and the Institute for Biophysical Research from the Krieger School of Arts and Sciences.
