Lauren Bradley, PhD (Councilor, 2016-2018)  

Rush University Medical Center, Chicago, IL

I believe that I am well-suited to serve on the TOS ehealth/mhealth Section, given my research interests and experiences. My program of research has focused on examining the long-term challenges faced by bariatric surgery patients and developing interventions to target weight regain in these patients. Little is known about the experience of bariatric surgery patients after the initial weight loss phase. To better understand this, I conducted a large-scale survey of bariatric patients. Based on these data, I developed and evaluated an acceptance-based behavioral intervention, which provided patients with psychological skills to respond to long-term weight-control challenges. One barrier to providing this treatment was the difficulty of patients to attend regular, in-person meetings due to geographical and time constraints. Therefore, I translated the group treatment to an online, interactive platform. To evaluate this program, I conducted an open trial, which demonstrated the intervention’s preliminary feasibility, acceptability and effectiveness in stopping and reversing postoperative weight regain. I am currently developing a larger-scale study to further evaluate this remotely-delivered program.

Sridevi Krishnan, PhD (Councilor, 2016-2018)

University of California Davis, Davis, CA

Dr. Krishnan’s research focuses on characterizing human variability in macronutrient metabolism with specific impacts on energy intake and expenditure, body weight maintenance, obesity, metabolic syndrome and type 2 diabetes. She has a Bachelors’ and a Masters’ degree in Food Science, Nutrition and Dietetics from Madras University, India. She completed her PhD in Nutritional Biology from University of California Davis, followed postdoctoral training at Texas Tech and UC Davis. She has worked on understanding how dietary macronutrient challenges, exercise interventions and dietary fatty acids impact body weight, fuel utilization and insulin resistance, as well as phenotyping and characterizing the role of HDL in cardio-metabolic health. She has focused on understanding interactions between physiological, psychological, social, endocrine and health behaviors, as part of her work so far. She identified that intrinsic motivation is improved in group exercise activities, which increases compliance to the exercise program, thereby impacting body weight maintenance, as part of a Zumba intervention study done in over weight/ obese and type 2 diabetic women (Krishnan et al, 2015, AJHB, 39(1):109-120). She has also investigated the interaction between circulating steroid hormones estradiol, progesterone and leptin, and whether they are associated with craving behaviors in women across their menstrual cycle (The FASEB Journal 30 (1 Supplement), 418.6-418.6). She is a member of the American Society for Nutrition, as well as The Obesity Society, and recently won the Translational Research Award Competition for an oral talk presented at ASN’s Experimental Biology conference.
