Purpose: This study investigates the interactions between your genes, your microbes, and your dietary intake and how these factors affect your health. In particular, we are interested in how these factors differ between individuals with and without type 2 diabetes. This study could help us better understand how type 2 diabetes develops and how we can better treat it using nutrition.
We are looking for: Men and women, ages 45 years or over with diagnosed type 2 diabetes or prediabetes
Time Commitment: One on-site study visit (approximately 2 hours), and the rest of the study can be completed at home on your own time (approximately 2 hours).
Study Location: Ithaca, NY (at Cornell University)
Honorarium and Benefit: $100

  • Purpose: The purpose of the proposed research is to characterize age-related metabolic dysfunction in human female skeletal muscle. This study will allow us to not only further understand the potential causes underlying observed changes in aging female skeletal muscle metabolism, but it will also provide evidence to develop better therapies to improve the overall quality of life for older women.
  • Time Commitment: 2 visits to the lab (Cornell Campus), the visits are 1-1.5hrs
  • Eligibility: Healthy adults ages 65-80 able to travel to Cornell campus who are okay with having their blood drawn and having a muscle biopsy
  • Compensation: $150

  • Purpose: This study investigates how aspects of metabolism, lifestyle, and age influence ovarian function, as well as how hormones differ in women with distinct patterns of follicle populations.
  • We are looking for: Women, ages 18 - 45 years, with a previous diagnosis of PCOS, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 3.5 - 4 hours spread over 3 study visits, 7 days off site (to wear a device that measures physical activity).
  • Study Location: Cornell University (Ithaca, NY)

  • Purpose: This study investigates ultrasound technology and aspects of age and adiposity influence ovarian morphology.
  • We are looking for: Women, ages 18 - 45 years, with a previous diagnosis of polycystic ovary syndrome (PCOS), who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 45-60 minutes

Healthy volunteers needed - Starch Intervention Study

Purpose: We study how your genes and gut microbes influence how you digest different starches. We will be screening participants in phase 1 of this study. If you meet our study criteria during phase 1, we will invite you to participate in phase 2. Phase 2 is a 6-week intervention study during which we will provide you with crackers containing different types of starches. During phase 2, we will need you to donate saliva and stool samples and fill out several questionnaires. Results from this study will contribute to the quest for personalized nutrition. 

We are looking for: Healthy men and women, ages 18 years and older 

Time Commitment
Phase 1: A 30-minute visit to Poole Lab, a saliva sample, and an online questionnaire

Phase 2: A 6-week dietary intervention study 

Study Location: Cornell University, Ithaca, NY 

Honorarium and Benefit
Phase 1 – A drawing for a $50 gift card

Phase 2 –  $200 upon completion of the study

  • Purpose: To evaluate how follicles develop in the ovaries of overweight women during weight loss, and to explore how changes in body composition, metabolic status, and reproductive hormones influence patterns of ovarian follicle development.
  • We are looking for: Women aged 18-35 with who have a BMI > 30, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 7-months of 2-4 study visits per week (20 minutes each) including a blood draw and transvaginal ultrasound scan, plus 3-4 longer visits (~2.5 hours) requiring an overnight fast.
  • Study Location: Cornell University (Ithaca, NY)
  • Honorarium and Benefit: Complimentary 6-month subscription to Nutrisystem D, Fitbit Device, and $2000 cash honorarium
  • ClinicalTrials.gov ID: NCT01785719
  • For more information, please email Professor Marla Lujan at: womensimaging@cornell.edu
  • Purpose: To compare how follicles develop in the ovaries of women that have regular menstrual cycles and those that have irregular/absent menstrual cycles, and to explore how body composition, metabolic status, and reproductive hormones are related to patterns of follicle development.
  • We are looking for: Women aged 18-35 with regular menstrual cycles who have a BMI < 25, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 4-6 weeks
  • Study Location: Cornell University (Ithaca, NY)
  • Honorarium and Benefit: $300
  • ClinicalTrials.gov ID: NCT01927432
  • For more information, please email Professor Marla Lujan at:
    womensimaging@cornell.edu
  • Purpose: The study investigates whether ultrasound features of the ovaries can be used to reliably diagnose different types of anovulatory disorders in women across all body types. The study will also try to establish whether ultrasound features of the ovary can reflect the degree of reproductive and metabolic problems that a woman with irregular or absent periods might be experiencing.
  • We are looking for: Women, ages 18-45 years with regular menstrual cycles, irregular menstrual cycles, or a previous diagnosis of PCOS
  • Time Commitment: 3.5 - 4 hours spread over 4 on-site study visits, 7 days off-site (to wear a device that measures physical activity).
  • Study Locations: New York City, NY
  • Honorarium and Benefit: $125
  • ClinicalTrials.gov ID: NCT03306849
