• NIH R21: Male-specific genomic mechanisms of transcriptional regulation of ME/CFS/SEID
  In an effort to provide insight into the key biological targets involved in sex-specific ME/CFS/SEID presentation, the main objective of this research proposal is to identify male-specific biomarkers and therapeutic targets of
  ME/CFS/SEID and provide insight into sex-specific disease onset and progression, which will lead to the better therapeutic intervention

• VA MERIT: Women vs. Men with GWI: Differences in Computational Models and Therapeutic Target
  We hypothesize that GWI affects regulatory function differently in women than in men, with implications on therapeutic management. The objective of this study is to improve our understanding of GWI pathogenesis in women by: (i) integrating data across several of the body’s regulatory systems, and (ii) mapping of dysfunctional signaling networks in GWI in each sex.

• NIH R01: Gender Differences in Myalgic Encepahlomyelitis/Chronic Fatigue Syndrome
  The proposed study will correct a gender imbalance in ME/CFS research. It may lead to phase 1 trials of targeted therapies designed to restore a normal balance of autonomic, immune and endocrine systems and thus, health in men and women.

• DoD CDMRR/GWIC: Brain-Immune Interactions as the Basis of Gulf War Illness: Gulf War Illness Consortium (GWIC)
  My role in the consortium is to provide core immune and genomic lab support to the investigators, and to evaluate the usefulness of biomarkers of inflammation in GWI.

• DoD CDMRP/GWIRC: Understanding Gulf War Illness: An Integrative Modeling Approach
  Integrate two animal models of GWI with human clinical data to pinpoint the underlying mechanisms of disease and target treatment more effectively to re-establish normal well-coordinated signaling interactions. Specifically, our more detailed understanding of the dysfunction associated with key metabolic pathways involved in GWI would greatly expedite the identification of promising biomarkers for improved diagnosis over the short-term as well as selection and testing of more targeted therapeutic interventions over the longer term that will address the underlying mechanisms of disease.

• VA MERIT: A Translational Medicine Approach to Gulf War Illness: From Cells to Therapy
  The objectives of the proposed study are to determine if intervening at these therapeutic targets selected via computational modeling will act as predicted and normalize immune and neuroendocrine function in an in vitro system. The study will have 2 phases: an exploration/ screening phase and a validation phase. The screening phase will be conducted on 17 repurposed drugs. These will be assessed in vitro using whole blood cultures from 40 GWI patients and 40 matched controls. The most promising 5 drugs will be validated in PBMCs from a new cohort of 40 GWI patients and 40 matched controls.

• CDC: Clinical Assessment of Patients with CFS and Biorepository Development
  Goal of project is to enable CFS researchers to provide a standardized approach to definition use in clinical diagnosis and management of CFS and improve standardization, integration, and sharing of CFS data to benefit research. Role is to oversee the clinical components of this work at our site, including the training and supervision of the clinical staff, and to assist the interdisciplinary team in the clinical utility of the findings.

• NIH R15: Genomic approach to find novel biomarkers and mechanisms of CFS/ME
  The employment of advanced genomic technologies and a well-rounded research approach will allow us to identify regulators of transcription that result in characteristic symptomatology associated with CFS/ME in female patients.

•  DoD GWIRP/ IIREA:Testing the Model: A Phase I/II Randomized Double Blind Placebo Control Trial of Therapeutics: Liposomal Glutathione and Curcumin
   The goal is to implement a phase I/II placebo control double blinded 3 arm study of liposomal glutathione, curcumin and placebo in GWI in 75 veterans with GWI (25 per arm) and assess the safety, feasibility and clinical response to the interventions;. Integrate repeat assessment and modeling of dynamic response to exercise challenge in order to map homeostatic pathways before and after 12 weeks of intervention. Finally, assess antioxidant and methylation-related metabolic status prior to, during, and after acute exercise in GWI subjects before and after these antioxidant interventions.
