Dr. Krystal Thomas-White, PhD

Dr. Krystal Thomas-White, Ph.D is the Senior Scientist at Evvy.

Dr Thomas-White is a microbiologist specializing in the female urogenital microbiome and how it relates to health and disease. In under 10 years she has over 20 peer-reviewed articles that have been cited over 1000 times. Her research explores how alterations in both the bladder and vaginal microbiomes are associated with common disorders (like UTIs, bacterial vaginosis, and incontinence) and how the microbiome changes in response to hormones throughout life, particularly during prengnacy, and menopause.  As senior scientist at Evvy she is excited to help bridge the gender health gap, and provide women with insight into a part of their bodies that has been too often overlooked.

How to Choose a Vaginal Microbiome Test

The vaginal microbiome has been getting more attention lately, and there are now a few different tests that you can do at home. But here's the thing: not all vaginal microbiome tests are made equal.

Race and the Vaginal Microbiome

Black women are more likely to develop bacterial vaginosis (BV) and yeast infections, and studies have shown there can be significant variations in the vaginal microbiomes of women from different racial groups. But we still don’t know enough about why this is the case, and how it’s linked to real life, tangible outcomes — this just isn’t good enough. In this article, we explore the relationship between race and the vaginal microbiome, plus what we still need to figure out.
