Watch Dionna Thomas, Environmental Health and Safety Professional at Emory University, share how she works with scientists and animal care staff and gives them advice on ways to stay safe in the workplace. She loves working in the science and biotech fields, and encourages girls to develop their math and science skills so that they can pursue careers in Science, Technology, Engineering and Math (STEM). There are many opportunities in those fields and girls should not let the boys have all the fun. Her advice to girls is to not be afraid to speak up. Many times the very thing that needs to be said or brought into the open, are just what they are thinking.
