Did you know that if you use your voice for more than five hours a day you are considered a professional voice user? We are Gillyanne Kayes and Jeremy Fisher. Our expertise in the field of voice coaching saw us appointed behind the scenes to this year’s ‘The Voice’ on ITV and led to singer, Cerys Mathews, nicknaming us the ‘Voice Gurus’ on her Sunday Morning show: http://ift.tt/2s96qj6.

Our bestselling books are described as must-reads for teachers, singers and students alike and we recently launched our One Minute Voice WarmUp app to help protect professional voice users from repetitive voice injury.

We’re on a mission to help people make the most of their voice - not just professionals, but day-to-day voice users including teachers, call centre workers, vicars, receptionists, personal trainers, business coaches and more.

Whether you want to know more about the science behind the voice (Gillyanne recently completed her PhD on the subject) or you're looking for more practical, voice-related advice, we can help...we'll be back at 1pmET to answer your questions, AMA!

Science AMA Series: We’re a group of scientists who use genomic sequencing technology to understand how viruses spread. Ask Us Anything!

See the source article by following the link below:

Hi Reddit, We are a group of scientists who use genomic sequencing technology to study the spread of viruses during outbreaks. Most recently we’ve been exploring the spread of Zika virus across the Americas. In order to understand how the virus has spread, we sequenced the virus genome from samples obtained from infected individuals, as well as from the mosquitoes that transmit the virus. Analysis of the genomic data allowed us to show how Zika virus spread across South America and Central America, into the Caribbean, and from there into Florida in the United States.

Our papers on Zika virus can be read for free here: Zika virus evolution and spread in the Americas by Metsky et al. Establishment and cryptic transmission of Zika virus in Brazil and the Americas by Faria et al. Genomic epidemiology reveals multiple introductions of Zika virus in the United States by Grubaugh et al.

The following scientists will be participating in this AMA:

Kristian Andersen, PhD, an Assistant Professor at The Scripps Research Institute and Director of Infectious Disease Genomics at the Scripps Translational Science Institute. Kristian has a background in host-pathogen evolution and immunology.

Nathan Grubaugh, PhD, a Research Associate at The Scripps Research Institute. Nathan is a postdoc in the Andersen Laboratory and is an expert on mosquito-borne viruses, such as Zika, chikungunya, and West Nile.

Hayden Metsky, a member of the Sabeti Lab at the Broad Institute of MIT and Harvard. Hayden is a graduate student in computer science at MIT and is interested in computational biology, machine learning, and their applications in viral genomics.

Shirlee Wohl, a member of the Sabeti Lab at the Broad Institute of MIT and Harvard. Shirlee is a graduate student in Systems Biology at Harvard and is interested in using genomic approaches to understand viral disease transmission.

Bronwyn MacInnis, PhD, is Associate Director of Malaria and Viral Genomics at the Broad Institute of MIT and Harvard, with experience in combining genomic technologies and epidemiology to understand and control infectious diseases affecting global health.

Jason Ladner, PhD, a member of the Center for Genome Sciences at USAMRIID. Jason is an evolutionary biologist who uses genetic data to understand the emergence and spread of pathogens.

Nick Loman, PhD, is a Professor of Microbial Genomics and Bioinformatics at the University of Birmingham. His research focuses on the use of sequencing for the diagnosis and surveillance of infectious diseases. He has applied portable nanopore sequencing in field conditions in Guinea during the Ebola epidemic and in a mobile laboratory that travelled through Brazil to investigate Zika.

We’ll be back at 1pm EST/ 10am PST to answer your questions. Ask us about genetics, genomics, virus biology, outbreak surveillance - ask us anything!
