My philosophy of care is to provide each child or adolescent with the most advanced medical care, in an individualized and comprehensive manner, to ensure their health and wellbeing. I promote shared decision making with the youth, in an age-appropriate manner, and their family.

My clinical activity focuses in the care of children with diabetes, including type 1, type 2 and other types of diabetes.

The overall goal of my research is the prevention of diabetes and its progression. I am interested in discovering the genetic and environmental causes of diabetes that can be leveraged for prevention and treatment. I also work to understand how to optimize clinical outcomes in pediatric diabetes.

Clinical Interests:

· Diabetes (type 1 diabetes, atypical diabetes, type 2 diabetes, monogenic diabetes, etc.)

Research Interests:

· Prediction and prevention of type 1 diabetes

· Genetics of type 1 diabetes

· Rare and atypical diabetes

· Heterogeneity of diabetes

Active Funded Research Projects:

- Type 1 diabetes genetic risk scores for the diagnosis of diabetes type in children of diverse racial and ethnic background (NIH NIDDK 1R01DK124395-01A1, PI Redondo)

- Type 1 diabetes genetic risk score in TrialNet (NIH NIDDK 1 R01 DK121843-01, PI Redondo)

- TrialNet Affiliate Clinical Center (NIH, site PI Tosur, Redondo’s role: Co-investigator)

- Center for Identification and Study of Individuals with Atypical Diabetes Mellitus (U54). Rare and Atypical Diabetes Network (RADIANT) (NIH 1 U54 DK118638, site PI Redondo)

- Immune Function and the Progression of Type 1 Diabetes (NIH NIAID P01 AI042288-25; PI Brusko; Redondo’s role: Site PI)

- Enhancement of biomarkers of type 1 diabetes (NIH 2 R01 DK112311-15A1, PI Pietropaolo; Redondo: Co-investigator)

- Diabetes-Docs: Physician Scientist Career Development Program (NIH NIDDK National K12; MPI: DiMeglio, Maahs; Redondo’s role: Program Scientific Review Committee)

- Addressing Social Needs and Behavioral Health Early in the Type 1 Diabetes Course to Mitigate Inequitable Health Outcomes among Socioeconomically Disadvantaged Minority Youth (BCM, PI Butler; Redondo: Co-investigator)

- Emergency Funding to Support Underserved T1D Populations Impacted by the COVID-19 Pandemic (Helmsley Charitable Trust, PI Redondo)
