Featured Student of the Institute for Regenerative Engineering: Keshia Ashe

Keshia AsheKeshia Ashe is one of my graduate students pursuing her Ph.D. in Chemical Engineering. Our paths crossed at the University of Virginia where she received her B.S. in Biomedical Engineering under the guidance of my former student, Dr. Edward Botchwey. I was really honored when she decided to move to Connecticut with me after finishing her undergraduate degree. Since joining my lab, she has explored her interests in bone and ligament regenerative engineering, controlled drug delivery, novel biodegradable biomaterials, nanotechnology, and biochemistry. In her four years as a graduate student, she has successfully published a book chapter on integrin-mediated cell adhesion, co-authored four highly cited publications in the new field of osteoinductive synthetic small molecules for bone regenerative engineering, and has begun to investigate the use of small molecules for ligament repair and regeneration. Specifically, Keshia’s research interests include:

1. Investigating the signaling pathways involved in collagen production and degradation during anterior cruciate ligament repair.

2. Synthesis and characterization of the novel inorganic-organic polyphophazene polymer.

3. Development and evaluation of small molecule releasing nanofibrous matrices for enhanced anterior cruciate ligament regeneration.

In addition to her research activities, she actively contributes to the development of her colleagues and underserved youth population as the vice president of the Controlled Release Society (CRS) and as a mentor to 20 high school students within the UConn Health Career Opportunity Programs (HCOP). Furthermore, she recently started a non-profit organization, ManyMentors, which uses online video conferencing to connect women and minority high school students with college students in the science, technology, engineering, and math (STEM) fields. It has been a pleasure advising Keshia through her many research endeavors and serving as a role model for her youth-focused activities. I anticipate nothing but the best as she continues to make an impact on not only academia, but also on the social climate of STEM.

Honored to Speak at NIH

Last June, I was invited to speak at the 25th anniversary celebration of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS). My talk, entitled “Meeting the Grand Challenges: Bold Ideas; Bold, Smart People; Organizations that Believe,” was based on my firm belief that we need those three things to successfully tackle challenges in medicine. Other keynote speakers included Professor Helen Lu, my former fellow at Drexel who is Associate Professor of Biomedical Engineering at Columbia University. I thank NIAMS for providing ongoing financial support for our research and for having the courage to believe in bold ideas. My talk was recently placed online. Please visit Meeting the Grand Challenges. I welcome your comments. Thank you.

A Bold, New Research Initiative

Recently, the National Science Foundation (NSF) Science and Technology Center Program reviewed our grant p re-proposal and invited us to develop a full application. It was particularly exciting for us because we scored in the top 10% of all submissions.

If the NSF approves our application, a unique center, focused on a regenerative engineering approach to complex tissue and organ regeneration, will be established with a base here at UConn. The proposed studies will assist in designing strategies to transition from individual tissues to complex organ regeneration. This program will focus on the integration of stem cell technology, regenerative biology, and Biomaterials science. Having a dedicated center will bring basic science, engineering, and medicine together under one umbrella. Our hope is that we will develop practical strategies which will ultimately lead to whole limb regeneration.

Congratulations to all the investigators who are participating in this proposal!

MRS Opening Invited Speech

Last week, I had the privilege of giving the opening invited speech for the Biomaterials and Tissue Regeneration Symposium at the Materials Research Society in Boston. I spoke about our Institute’s work in building matrices for bone regeneration using polymeric materials and ceramics. I focused on some of our new theories regarding the design of matrix systems that can be inductive for Bone. I want to thank my co-authors of this work and I also want to provide a special thanks to Professor Mei Wei who invited me to give the lecture at the meeting.

American Institute of Chemical Engineers

I recently attended the American Institute of Chemical Engineers (AICHE) meeting where I was elected a Fellow of the Institute. Previously I was named one of the 100 Chemical Engineers of the Modern Era by the AICHE for my work in the design of polymer-ceramic systems for bone repair and regeneration. An award such as that is only possible with the support of a large number of students and colleagues who have worked with me over the past years. Some of the earliest individuals included Dr. Hoda Elgendy, Dr. Maria Norman, and Dr. Mohammed Attawia my first fellows, and Dr. Carol Morris, my first graduate student. They joined my lab at M.I.T. when I was still an orthopaedic surgery resident and worked on some of the seminal studies in the field. To them, and others, I give my thanks.

Third World Academy of Sciences

photo_thirdworldmeeting-400x300I had the great fortune to meet with the leaders of the African Academy of Sciences (Dr. Mohamed Hassan, President) and the Third World Academy of Sciences Dr. C.N.R. Rao, former President) at its recent annual meeting. I discussed our new National Science Foundation Science and Technology Center application and have asked them both to join our advisory board. Our Institute has forged collaborations with institutions in India which have included the exchange of students. In addition, faculty in our Institute have been involved in the establishment of the African Institute of Science and Technology. I am very proud of our Institute’s work in the international arena in teaching and research.

Helen I. Moorehead-Laurencin, M.D., Sex and Gender Forum 2011 at Drexel University

Sam LaurencinI was really excited to attend the Helen I. Moorehead-Laurencin, M.D., Sex and Gender Forum at Drexel University. Now in its 10th year, the Forum honors the memory of my mother, an extraordinary physician who worked in the inner city of Philadelphia. Dr. Helen Laurencin was very passionate about clinical care, research and education, and served as a quiet leader for the community. The Forum, sponsored by the Institute for Women’s Health and Leadership at Drexel, is a fitting tribute to her work and her legacy. Attending the Forum was the next generation member of the Laurencin medical family, Sam Laurencin. He is completing an M.D. at Drexel Medical School, and his Ph.D. in Chemical Engineering. Sam plans to enter a career as an academic orthopaedic surgeon.

I am very grateful to the leadership of Drexel including Lynn Yeakel, Dr. Michelle Follen, and Dr. Sandra Urdaneta Hartmann for putting on such a fine program.

U.S.-India Collaboration
