This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program, with a focus on the physics and applications of optical waveguiding in the CROW (Coupled Resonator Optical Waveguide) device structure. The CROW structure is suitable as the foundation of this project because it offers a very high four-wave mixing nonlinearity based on the slow-light effects on each of the pump, signal and idler modes. Since the output depends quadratically on the propagation length (in the low power regime), it is important to realize long CROWs.

This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program, which focused on the physics and applications of optical waveguiding in the CROW (Coupled Resonator Optical Waveguide) structure. The CROW structure is suitable as the foundation of this project because it offers a very high four-wave mixing (FWM) nonlinearity based on the slow-light effects on each of the pump, signal and idler modes. The triple resonance effects can result in a large improvement of the nonlinear coefficient even with a modest improvement of the slowing factor. However, understanding the effects of disorder in CROWs is important, since it can limit the amount of slowing that can be achieved, and hence, the enhancement of slow-light enhanced nonlinearity.

This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program. The project’s focus is the science, engineering and applications of low-power (milliwatt class) nonlinear optics using a novel type of waveguide, the Coupled Resonator Optical Waveguide (CROW). Examples of applications of the nonlinear effects that were studied in this project are wavelength conversion of high speed modulated signals and correlated photon-pair generation.

This NSF-funded project is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program. The project’s focus is the science, engineering and applications of low-power (milliwatt class) nonlinear optics using CROWs. Coupled resonator optical waveguides (CROWs) are linear sequences of micro-resonators fabricated on a chip that guide light from one end of the chain to the other by nearest-neighbor coupling.

OBJECTIVES/SPECIFIC AIMS: The clinical and translational research workforce is in jeopardy due to investigator attrition and competing demands upon researchers. Resilience and wisdom are measurable traits that can be acquired. The aim of this study was to examine a pilot curricular intervention promoting resilience and wisdom formation in early-career translational researchers. METHODS/STUDY POPULATION: We conducted a prospective, mixed-methods evaluation of a curricular intervention promoting the development of wisdom and resilience among junior faculty in a career development program. Six 90 minute sessions were delivered between September 2017 and January 2018. Pre- and post- resilience and wisdom were measured using the Connor Davidson Resilience Scale and 3D-Wisdom Scale. Individual semi-structured interviews were conducted before and after the intervention RESULTS/ANTICIPATED RESULTS: Five scholars participated. Median resilience and wisdom scores revealed moderate levels of each trait; pre- and post-scores were not significantly different. Four themes emerged from the analysis of interview transcripts: 1. “Success” broadly defined; 2. Adversity threatens success; 3. Community breeds resilience; and 4. Wisdom formation parallels growth towards independence. DISCUSSION/SIGNIFICANCE OF IMPACT: An intervention aimed at developing capacities of resilience and wisdom is feasibly delivered to early career researchers. The relationship between these capacities and the sustainability of a research career warrants additional study.

Abstract We surveyed awardees of the Minority HIV Investigator Mentoring Program (MHIMP) of the AIDS Clinical Trials Group. Most reported clinical specialization in infectious diseases or HIV medicine (86%), and all but 1 (95%) are engaged in medical/health sciences research. The MHIMP helped retain early-career minority investigators in HIV/AIDS-related research.

Health science researchers need training and support to effectively pursue independence in their research careers. Little data exist regarding the specific resources that faculty researchers have found or would find useful. In this study, we aimed to better understand the needs of health science researchers to develop recommendations for effective career development programming. The authors conducted a multi-method evaluation of early-career researcher faculty needs beginning by using post-session satisfaction surveys to assess the value of a long-standing “K-Club” seminar, which educates and supports those pursuing NIH Career Development (K) awards or similar. The authors then collected in-depth views on career development needs through a series of focus groups conducted with health science researchers at three career stages: early career, award-seeking junior faculty; mid-career faculty who have obtained some extramural funding; senior faculty who serve as mentors for early/mid-career faculty. Participants who attended the existing K-Club strongly endorse the program in supporting their career goals. Focus group participants described specific areas for program expansion that would add value across career stages: more flexible training options, conducted in smaller group settings with immediate feedback provided; more formalized training and resources for senior research mentors; in-depth guidance on individualized grantsmanship. The authors propose program development guidelines for helping researchers achieve research independence and success. Findings indicate that a broad-reaching K-Club style educational seminar can serve as a valuable foundation supporting professional development. The addition of tailored programs delivered across diverse platforms are predicted to heighten career development success.

Objective Our institutional Women in Medicine & Science Program (formerly the Office of Women in Medicine and Science) developed the Early Career Development Program for Women to promote the careers of women faculty. At 6 monthly sessions, participants learn relevant content (imposter syndrome, strengths, change style, career management, assertive communication, feedback, personal influence, conflict management, negotiation, importance of mentors, resilience, and self-care); exchange ideas; and expand their professional networks. Here, we report changes in participants’ career skills/knowledge, confidence, and perceptions of the current environment after attending the program. Method Between 2014 and 2017, participants (N = 65) completed pre- and post-program surveys that assessed career knowledge and skills, confidence, and perceptions of the current environment and provided program feedback. Results Most skills showed pre–post significant improvement. The greatest increases occurred in knowing paths to promotion, tailoring communication style, ability to manage conflict, and ability to handle personal–professional role balance. Women reported a significant increase for all items measuring confidence. Among these items, establishing networks, understanding institutional culture, providing feedback, motivating others, strategic planning, delegating, and conflict management had the largest increases. Overall, 89.3% of respondents rated the program impact as very strong/profound, 98.5% rated the concepts as essential, 95.2% rated the skills as essential, and 90.8% rated the sense of community with women in their class as very/extremely close. Conclusions Work-related skills/knowledge, confidence, and perceptions of the current environment increased significantly among program participants. These early-career women faculty indicated that the program augmented the skills needed to develop their careers in an academic medical center.
