Graduate student wins top poster prize at American Astronomical Society meeting

Jan 18, 2011

At the January 2011 annual meeting of the American Astronomical Society in Seattle, UNC Chapel Hill graduate student Amanda Moffett won one of the coveted Chambliss Astronomy Achievement Awards for her poster presentation on "Extended UV Disks in Low-Mass E/S0 Galaxies and Their Relation to Disk Building." Amanda's research has revealed unexpected complexity in the interpretation of ultraviolet light from young, massive stars in the extreme outer reaches of galaxy disks: the optically dim, extended UV or "XUV" disks discovered by NASA's GALEX mission are more common in stereotypically dead galaxies (remnants of violent galaxy mergers) than in actively growing ones (like our own spiral galaxy, the Milky Way). However, an intriguing population of remnant galaxies that may be regenerating spiral structure shows a low frequency of XUV disks, consistent with the frequency seen in normal spirals. Amanda's work has been submitted to the Astrophysical Journal Letters with adviser Sheila Kannappan and collaborators Andrew Baker and Seppo Laine.

Custom Trike Brake System
Click for larger version

Frances Low, who received her BS in physics in May 2009, has been selected as a finalist in the student design competition at the RESNA (Rehabilitation Engineering and Assistive Technology Society of North America) conference to be held in New Orleans in June. Frances will demonstrate her design in the Exhibit Hall, and if selected as a winner she will give a presentation in a special platform session.

Frances' entry, which she developed in the BMME 840 "Rehabilitation Engineering Design" class taught by Prof. Richard Goldberg, consists of a custom tricycle brake system that allows a teenage girl with reduced motor control to brake her tricycle easily and independently, which was difficult before because she had trouble using the conventional brake levers on the tricycle. Therefore, the custom brake system allows her to activate the brakes using a rotational hand motion and incorporates mechanical advantage to allow her to brake more easily using less strength. Frances plans to study Mechanical Engineering next year at NCSU to prepare for a career in developing robotic vehicles for space exploration. Congratulations, Frances!

Recent graduate Kwan Skinner awarded Carolina Postdoctoral Fellowship for Faculty Diversity

Feb 25, 2009

Kwan Skinner, a Durham native who received his undergraduate degree in Physics and his PhD in Materials Science from UNC, has been awarded a fellowship from the Carolina Postdoctoral Program for Faculty Diversity. The program is designed to develop scholars from underrepresented groups for possible tenure track appointments at the UNC-Chapel Hill or at other research universities. Dr. Fred Hall has held a similar appointment in the Physics & Astronomy Department since Fall 2007.

Dr. Skinner's research, which he conducts in collaboration with Prof. Sean Washburn, is focused on the construction of nanowire arrays directly onto commercially available silicon chips using electrochemical deposition as the fabrication route. Electrochemistry is a fast and cost-effective method that permits the deposition of metal and semiconducting species onto arbitrary conducting substrates. When the substrate contains a periodic and porous substructure, the deposited metal will preferentially fill the pores of the electrode. Dr. Skinner has fabricated arrays composed of various materials including metals, semiconductors and conducting polymers for applications ranging from magnetically actuable probes for bio-sensing to electrical elements for nanoscale circuits. However, the time-consuming necessity of removing the nanowires from their host substrate before they can be used in a device limits their usefulness, so Dr. Skinner's direct-construction techniques promise a considerable advance in the field.

Dr. Skinner will use his postdoctoral period to create further academic connections with researchers in the scientific community at neighboring universities and through academic conferences. He will also take part in the K-12 educational activities of the nanoscience group. When he is not engaged in scientific work or educational outreach, he enjoys doing anything related to food, especially watching the Food Network and tinkering in the kitchen.

Hugon Karwowski wins Johnston Teaching Excellence Award

Apr 11, 2008 UNC Physics professor Hugon Karwowski

Prof. Hugon Karwowski has received a 2008 Johnston Award for Teaching Excellence. Nominations for this award come from Johnston Scholars, recipients of UNC-Chapel Hill's premier need-based scholarships. Every year approximately 70 entering freshmen are chosen to be Johnston Scholars, based on outstanding high school records and leadership potential. The citation for Prof. Karwowski's award reads as follows:

Professor Karwowski's devotion to teaching undergraduates can best be described as "fanatical." Despite a distinguished career as a nuclear physicist, he is best known by students as an exemplary professor, consistently described as "considerate," "extremely approachable," "always available," "humorous," "bright," and even "crazy."

Questions are "expected, not encouraged" in Dr. Karwowski's courses. He teaches by helping students think through ideas, rather than simply lecturing. He eschews examples from the textbook. Instead, he develops his own clever means of illustrating physics concepts which are "memorable as well as pedagogically sound," using examples which include beavers, toys, sleds, and other scenarios rarely found in an introductory physics course.

One specific example quoted by a former student: "He challenged us regularly in class to tackle design problems that integrated all our undergraduate knowledge and applied it to creating a feasible solution. One such problem that I particularly remember was posed to us on Valentine's Day. He challenged us to design a system that could monitor the heart rate and the amount of blood drips per minute of an individual whose heart was pierced by Cupid's arrow. The problem initially seemed to have no relevance with electronics, but once our class began to think and come up with new ideas, we were able to apply our electronics knowledge to come up with an innovative solution. Several problems like these not only made the materials learnt in class digestible, but also helped me retain the information and observe how the classroom knowledge can be applied in practice."

Dr. Karwowski is extremely dedicated to helping students succeed outside of class as well, spending "hours upon hours with students in office hours and with review sessions," sending multiple e-mails per day, and offering advice on everything from grad schools to building a distortion-free speaker system. Even in his larger classes, he knows everyone's name and regularly greets students from previous semesters. According to one student, "all 50 people [in his class] would vouch for his being approachable."

He is widely known for working nights and weekends; one student sent him an e-mail Friday night, and in his prompt response, he offered an impromptu help session that Saturday evening. According to the chair of the Physics and Astronomy Department, "he never says he has something more important to do than help a student understand a physics concept...This is contagious!"

Professor Karwowski's tremendous efforts to impart his passion for physics and to ensure students learn clearly set him apart among faculty. As one interviewed student said: "He is far and away the best professor I have ever had at Carolina...Make sure he wins an award!"

Sean Washburn named Outstanding Referee

UNC Physics professor Sean Washburn

Professor Sean Washburn has been named an Outstanding Referee by the American Physical Society (APS), one of only 534 of the 42,000 active referees for the physics journals published by the APS. This is the first year of this very selective award, and the physicists chosen are truly exceptional in their contributions to the physics community by their hard work and careful attention to the peer review process. The efforts of the honorees in peer review not only keep the standards of the journals at a high level, but in many cases also help authors to improve the quality and readability of their articles-even those that are not published by APS. The basis for choosing the honorees was the quality, number and timeliness of their reports. The names of this year's honorees are listed at http://publish.aps.org/OutstandingReferees, and will be printed in each APS journal. Prof. Washburn is to be congratulated and thanked for his outstanding service to the physics community.


Paul Frampton's research on black holes discussed in New Scientist

An article in the January 18, 2008 issue of New Scientist discusses a recent result obtained by Prof. Paul Frampton in collaboration with Stephen Hsu and David Reeb of the University of Oregon and Thomas Kephart of Vanderbilt University. Their calculations build on a fact pointed out in 2003 by Prof. Jack Ng and Kephart that known black holes dominate the entropy; as well as on more recent work by Frampton and Kephart about the entropy of ordinary matter. The paper discussed in New Scientist explains how comparably big entropies can exist even outside of black holes in special configurations of normal matter called Monsters.

Graduate student Brian Collins wins award at conference

UNC Physics graduate student Brian A. Collins Graduate student Brian Collins has been selected as the Outstanding Student Paper Award winner for the best poster presentation at the 24th North American Conference on Molecular Beam Epitaxy (NAMBE).

Graduate student Guang Yang wins Radiological Society prize

Guang Yang, a physics graduate student working under the supervision of Prof. Otto Zhou, has won the RSNA Trainee Research Prize from the Radiological Society of North America (RSNA) at its 2007 meeting. This meeting is the world's largest professional meeting on medical science and technology. It hosts more than 60,000 attendees from around the world every year. The RSNA Trainee Research Prizes are given for the best paper or poster in each subspecialty presented by a resident/physics trainee, fellow or medical student at the RSNA meeting. The Research Trainee Prize consists of $1000 and a certificate.

Guang Yang' paper, "Novel Gantry-free Digital Breast Tomosynthesis (DBT) System Using a Stationary Multibeam Field Emission X-ray Source Array Based on Carbon Nanotubes," describes an interdisciplinary study in which the authors developed a novel multibeam field emission x-ray source array based on carbon nanotubes, and built a digital breast tomosynthesis system (Argus) for breast imaging. Argus is the first stationary tomosynthesis system for clinical diagnostic imaging. Compared to its clinical counterparts, the Argus system can provide diagnostic images with similar quality, but the total imaging time is reduced by factor of 10 to 100. This research result shows great potential for clinical applications.

The research was supported by the National Cancer Institute and UNC's Lineberger Comprehensive Cancer Center.

The co-authors of this paper are: Guang Yang, Ramya Rajama, Guohua Cao, Shabana Sultana, David Lalush, Jianping Lu, and Otto Zhou.
