Human Genetics As a graduate student at Oxford and
postdoctoral fellow with
Eric Lander at the
Broad Institute, Sabeti developed a family of statistical tests that identify regions of the genome under
positive natural selection, by identifying common genetic variants found on unusually long
haplotypes. Her tests, extended haplotype homozygosity (EHH), the long-range haplotype (LRH) test, and cross population extended haplotype homozygosity (XP-EHH), are designed to detect advantageous mutations whose frequency in human populations has risen rapidly over the last 10,000 years.
Infectious Disease In 2014, having worked for a decade together in West Africa on Lassa fever and other infectious diseases, Sabeti and
Christian Happi, a Cameroonian geneticist, and their teams launched the African Center of Excellence for Genomics of Infectious Disease (ACEGID) to enhance pathogen surveillance and education in Africa. Their efforts in the
Ebola outbreak in West Africa helped identify the first cases in Sierra Leone and Nigeria, and advanced
genomic sequencing technology to identify a single point of infection from an animal reservoir to a human.
RNA changes further suggested that the first human infection was followed by exclusive human to human transmissions. They also showed the virus was mutating to be able to infect human cells more easily. Sabeti's team continued to support outbreak response, developing and deploying genomic and computational tools to elucidate the origins, evolution, and community transmission of viruses. During the Zika epidemic in 2016, Sabeti's team assembled the largest sequencing study of the virus and showed the virus was circulating undetected for many months. During the 2018 Lassa fever outbreak in Nigeria, her and Happi's team rapidly sequenced the virus on ground in the country, providing real-time feedback to the Nigeria CDC on the origins and spread of the outbreak. During COVID-19, her team led genomic investigations that elucidated the first superspreader events, variants of concern, and transmission from vaccinated individuals. In 2019, Sabeti and Happi's teams were "awarded funding from the TED Audacious Project to build Sentinel, a pandemic pre-emption and response system."
Other contributions Her lab developed a family of statistical tests to detect and characterize correlations in datasets of any kind, maximal information non-parametric exploration (MINE). In February 2021 Sabeti co-authored a paper on how a certain level of
COVID-19 anti-bodies may provide lasting protection against the virus, studying 4300 employees of
SpaceX with its CEO
Elon Musk.
Outreach and Teaching In May 2015, she delivered a
TED Talk, called "How we'll fight the next deadly virus." In September 2021, Sabeti joined the YouTube channel
Crash Course to host its series on Outbreak Science. Sabeti hosted the Against All Odds video series with the goal of explaining statistics to high school and college students. Sabeti is an annual participant in the Distinguished Lecture Series at the acclaimed
Research Science Institute at MIT for high school students. == Awards and honors ==
