Professors James McGrath, Ph.D. (Biomedical Engineering) and Jeremy Taylor, M.D. (Nephrology) were recently awarded a Coulter Foundation grant to develop a wearable hemodialysis system using a breakthrough silicon nanomembrane technology originally developed at the University of Rochester. Taking advantage of the extraordinary permeability and selectivity of the nanomembranes, the team hopes to eventually replace clinic-based hemodialysis with a much smaller continuous dialysis system that allows patients to remain mobile. As clinical dialysis requires hours of immobilization during dialysis and fluctuations in toxin levels that cause side effects, a continuous wearable system would provide dramatic improvement in patient lifestyle.

U.S. Rep. Louise Slaughter will join UR President Joel Seligman, Hajim School Dean Rob Clark, and Department of Physics and Astronomy Chair Nicholas Bigelow today for the opening of the Integrated Nanosystems Center. A news conference is scheduled for 1:30 p.m. in Munnerlyn Atrium, Goergen Hall. The facility brings together the disciplines of physics, optics, chemistry, biomedicine, and bioengineering to enable research in the fields of nanoscience and nanotechnology.

BME student Kelli Summers presenting
her research at this year's undergraduate symposium.

Congratulations to BME undergraduate student Kelli Summers, who has been selected as a 2011-2012 Fulbright Scholar to conduct research on Implementing a Strategy to Combat Child Pneumonia Fatalities in Ghanaian Rural Hospitals.

Kelli will leave for Malawi at the end of May to learn about conducting anthropological research and begin her Fulbright research. She will then travel to St. Francis Xavier Hospital in Assin Foso, Ghana for her Fulbright year and will collaborate with a physician she met during a volunteer experience in 2009. She hopes to create modifications to the World Health Organization's Child Lung Health Program (CLHP) through the use of a focus group and then implement it in the Children's Ward to ultimately decrease the child mortality rate at St. Francis and provide a model for other hospitals in the area.

Her research builds upon the CLHP, which contains protocols to assess and treat childhood pneumonia in developing countries in an effort to decrease the child mortality rate. After conducting extensive literary research, Kelli believes three major problems of the CLHP prevail:

• Disconnect between the policy-makers and the hospital staff implementing the program
• Lack of cultural specificity in nurse education and expectations for patient receptiveness
• Lack of diagnostic technology - specifically pulse oximeters

Kelli has been the immediate past president of the Student Chapter of BMES, and has been involved with BMES since she was a freshman. As co-founder and co-President of UR Genocide Intervention, Kelli helped to raise awareness, advocate to local politicians, raise money for victims, and secure scholarships for Sudanese students to come to the University of Rochester through Banaa. Additionally, Kelli has been tutoring local refugee high school and middle school kids every Saturday for the past year and a half. It's been interesting interacting with them, said Kelli about the kids, It's incredible to see how much they've grown in such a short time. Kelli has also been working in Professor McGrath's Laboratory since her sophomore year conducting research under an NIH grant on Mechanisms Underlying Collective Cell Migration in Vitro. She won the Presidential Research Award this year and is currently working on a peer-reviewed paper as the primary author to submit to the Annals of Biomedical Engineering.

Congratulations to the RCBU and BME students whose work was recognized at the prestigious annual University of Rochester Undergraduate Research Exposition 2011. Undergraduate students from RCBU and BME research laboratories participated in the symposium. BME undergrads Benjamin Freedman '11 and Kelli Summers '11 were both invited to speak at the Engineering and Applied Sciences Symposium Talks.

Freedman discussed his work, What is Q-Angle really measuring? A novel alternative to predict patellar maltracking, which received the Dean's Award. Summers spoke about her research with Dr. James McGrath, Mechanisms Underlying Collective Cell Migration in Vitro, which was recognized by President Seligman with the President's Award. Aaron Zakrzewski (ME '11), mentored by Mechanical Engineering Professor Sheryl Gracewski, gave an oral presentation of his research titled Natural frequency of bubbles within rigid and compliant tubes. Aaron also received a Deans' Award for Undergraduate Research in Engineering and Applied Sciences for his presentation. In addition, five of the seven poster exhibitions from the Hajim School of Engineering and Applied Sciences were by BME students:

Molly Boutin (Benoit Lab) BME '11

Jessica Snyder, a biophysics graduate student and member of Jim McGrath's biomedical engineering lab, credits her work as an elite cross-country skier in helping her become the third place female finisher in the Rochester Chase Corporate Challenge last May, which contributed to the University of Rochester (UR) team's win of the mixed team title. The four-member team will now travel to Johannesburg, South Africa for the Championship in March.

Joining Jessica will be Luke Mortensen, a graduate student in Biomedical Engineering; Chris Hine, a graduate student in biochemistry and biophysics; and Christina Devries, a technical associate at the Center for Human Genetics and Molecular Pediatric Disease.

Recent Ph.D. graduate Tom Gaborski is realizing his dream of entrepreneurship as VP of Life Sciences at UR spinoff, SiMPore, Inc. Tom helped found SiMPore Inc. in 2007 while he was a graduate student in the Ph.D. program. The company actually grew out of a chance experiment conducted by Tom and Chris Striemer, who was then a Ph.D. candidate in Electrical and Computer Engineering. Chris had inadvertently made the world’s thinnest nanoporous membrane while developing new materials for silicon-based lasers. Tom and Chris designed and conducted experiments to test if the nanoscale pores could be used to separate proteins of different sizes and charges and discovered that they did so very efficiently. The commercial potential of this discovery was immediately obvious to Tom.

Along with their advisors, Chris and Tom founded SiMPore to commercialize the discovery. The company now employs 9 people and started selling membranes in January of 2009. Sales have been steadily increasing as advertising efforts payoff and global interest in the material grows. Tom wears many hats in the small start-up but his primary job is to lead the company in its development of products for the biological sciences. Under Tom’s leadership, devices for protein and DNA purification are already in the SiMPore product pipeline.

SiMPore Inc., a company commercializing nanotechnology invented at the University of Rochester, has developed an ultra-thin microscope slide that significantly improves high-resolution imaging of nanoscale materials such as proteins, viruses, and carbon nanotubes. This is the first commercial application of a unique nanomembrane initially reported in Nature in 2007.

SiMPore, Inc., a spin-off company founded by engineers on River Campus, recently won the Golden Horseshoe Business Challenge, a $100,000 prize recognizing its business plan as the best in a region encompassing western New York and eastern Ontario. SiMPore also attracted $1.25 million in investments financed primarily by local Rochester high net worth individuals. In addition to VP of Life Sciences Tom Gaborski, (BME Ph.D. 2008), this venture involves interactions with numerous BME faculty members and students.

On April 1, 2008 UR/SiMPore, Inc. began a NYSTAR-sponsored collaboration to commercialize pnc-Si membranes. The Technology Transfer Incentive Program (TTIP) award was one of only 2 University-based technologies supported by NYSTAR this year. Specifically, University of Rochester was awarded $473,000 to work with SiMPore to use previously developed porous-silicon ultra filtration technology in biochemical separation.
