Current KL2 Scholars

  • Talea M. Cornelius, PhD, MSW

    • Instructor in Medical Sciences

    Project: Reactions to Acute Care and Hospitalization

    Dr. Cornelius conducts research focused on understanding health behaviors in the social context in which they are performed. In particular, her work explores processes of health-related power and influence, interdependence in change over time, and how partner support can both facilitate and/or undermine health-promoting behaviors. Recent projects include an examination of how the presence of close others (i.e., a spouse/partner, a child) in the Emergency Department (ED) impacts patients' ED experience, the effect of romantic partners on blood pressure both short and long term, and a qualitative study describing couples' experiences following an acute coronary syndrome (ACS). Dr. Cornelius is also exploring novel applications of dyadic analysis to interdependent, individual-level processes.

  • Andrea T. Duran, PhD, MPhil, MS

    • Assistant Professor, Medical Science (in Medicine)

    Project: Implementing Telehealth-enhanced Hybrid Cardiac Rehabilitation among Acute Coronary Syndrome Survivors: A Pilot Randomized Controlled Trial

    Very short bio: Dr. Duran is an Assistant Professor of Medical Science at the Center for Behavioral Cardiovascular Health at Columbia University Irving Medical Center, as well as a Robert Wood Johnson Foundation Health Policy Research Scholar Alumna. She received her PhD in Kinesiology at Columbia University and completed her post-doctoral fellowship in Implementation Science in the Department of Medicine at Columbia University Irving Medical Center. Her current research focuses on developing equitable, theory-informed, multilevel implementation strategies for integrating evidence-based physical activity guidelines and novel behavioral interventions into diverse healthcare and community settings, with the aim of reducing health disparities in the prevention and treatment of cardiovascular disease (CVD). Dr. Duran’s interest in the behavioral sciences and CVD prevention is driven by her dedication to address the high rates of physical inactivity and CVD in disadvantaged communities.

  • Lisa Eisler, MD

    • Assistant Professor, Department of Anesthesiology

    Project: Predicting and Improving Management of Allogeneic Transfusion in Pediatric Patients Undergoing Spine Surgery

    Dr. Eisler is a practicing pediatric anesthesiologist with an interest in how preparation for surgery improves postoperative outcomes. Her specific clinical question at this stage of her research career is whether optimization for childhood spinal fusion surgery can impact the need for perioperative blood transfusion and related complications. She is also interested in targeting pediatric populations with multiple comorbidities for preoperative assessment and intervention, with outcomes of interest ranging from immediate postoperative events to patient- and parent-reported outcomes such as satisfaction. She is currently working towards a Master’s of Science in Patient-Oriented Research at the Mailman School of Public Health. She completed her anesthesiology and subspecialty training at Columbia University Irving Medical Center. She holds a medical degree from Johns Hopkins University School of Medicine, and an undergraduate degree from Harvard College.

  • Cristina R. Fern├índez, MD, MPH, FAAP

    • Assistant Professor, Department of Pediatrics

    Project: Associations between prenatal food insecurity and inadequate physical activity and feeding practices, cardiac autonomic function, and emotional regulation to stress in high-risk infants

    Dr. Fernández is an Assistant Professor of Pediatrics at the Columbia University Irving Medical Center and cares for newborns in the Well Baby Nursery of the Morgan Stanley Children’s Hospital of NewYork-Presbyterian. Her innovative research focuses on the areas of food insecurity, diet-related disparities, and issues in development and health maintenance in vulnerable child populations. As an emerging investigator with burgeoning expertise in newborn care, Dr. Fernández assists in coordination of clinical research initiatives with the newborn nursery population. 

    She received her MPH from the Yale School of Public Health and subsequently completed her medical training at the Columbia University Vagelos College of Physicians & Surgeons. She subsequently completed her residency in pediatrics at the NewYork-Presbyterian Hospital/Columbia University Irving Medical Center and a primary care research fellowship in community health at the Columbia University Irving Medical Center.

  • Alexander Melamed, MD, MPH

    • Assistant Professor, Department of Obstetrics & Gynecology

    Project: A predictive model to identify ovarian cancer patients who will benefit from neoadjuvant chemotherapy

     

    Alexander Melamed, MD, MPH is an Assistant Professor in the Division of Gynecologic Oncology in the Department of Obstetrics and Gynecology at NewYork-Presbyterian/Columbia University Medical Center. He provides medical and surgical care to women with cancers of the reproductive system including ovarian, uterine, cervical, and vulvar cancer. Before joining the faculty at Columbia University, he completed residency in Obstetrics and Gynecology and fellowship in Gynecologic Oncology at the Harvard-affiliated programs of Massachusetts General Hospital and Brigham and Women’s Hospital. In addition to caring for patients, he also conducts research into how variation in treatment affects cancer outcomes in the real world. His research interests and expertise center on harnessing “big data” to learn how we can improve surgical outcomes among women receiving treatment for gynecologic cancers. Specifically, his work has helped to define the role of minimally invasive surgery in gynecologic oncology and identified strategies that reduce unnecessary side effects in the treatment of ovarian cancer. These and other studies have been published in leading medical journals including The New England Journal of Medicine, JAMA Oncology, and BMJ.

  • Caleb Miles, PhD

    • Assistant Professor, Department of Biostatistics

    Project: Personalizing treatment decisions and understanding causal mechanisms for functional and occupational outcomes among patients with schizophrenia

     

    Dr. Caleb Miles works on developing semiparametric methods for causal inference and applying them to problems in public health. His applied work has largely been in HIV/AIDS, and he has more recently begun to work on psychiatric applications as well. Dr. Miles' current methodological research interests include the intersection between machine learning and causal inference, interference, mediation analysis, and measurement error.

    • Assistant Professor, College of Dental Medicine

    Project: Extracellular vesicle-mediated immune modulation in oral squamous cell carcinoma

    Dr. Momen-Heravi is an Assistant Professor in the Columbia University College of Dental Medicine. After obtaining her DDS, she completed several years of fundamental research in molecular biology and immunology at Harvard Medical School, Brigham and Women’s Hospital, and the University of Massachusetts Medical School. She received a PhD degree from the University of Westminster, UK, in molecular biology/biotechnology. She also received an MPH degree from Harvard University, with a concentration in quantitative methods and biostatistics. Dr. Momen-Heravi completed a clinical residency and received a Master of Science in Periodontics from Columbia University College of Dental Medicine and is a board-certified periodontist.

    As a clinician scientist, Dr. Momen-Heravi’s work is focused on understanding the interplay between the immune system, tumor microenvironment, and tumors to identify actionable molecular targets for head and neck cancer and other solid tumor treatments. She also studies the biological basis for cancer health disparities and is passionate about combining different disciplines, including translational research, bioinformatics and biostatistics, and epidemiology and community outreach in her research.
