When Dr. Poonnada Jiraanont was a PhD candidate, she was interested in research about Autistic Spectrum Disorder. During her visit as a visiting scholar to the MIND Institute, University of California Davis, CA, she had a good chance to study and perform research on Fragile X Syndrome (FXS) under supervision of Professor Flora Tassone; subsequently she published four papers related to FXS (mosaicism and premutations). After receiving her PhD. (Neuroscience) from Mahidol University, she continues working on FXS particularly screening of premutation carriers in Thailand which has never been studied before. Currently, there are 3 ongoing projects about FXS: 1) Attitude towards carrier and prenatal screenings of Fragile X Syndrome in Thai reproductive women, 2) Carriers Screenings of Fragile X Syndrome: Case study at Sirindhorn Hospital, and 3) Mobile phone application for Fragile X syndrome. She is currently collaborating with Professor Tassone and plans to go to the MIND Wet Lab in 2021 when the COVID-19 situation allows.
In addition, Dr. Poonnada has a background on clinical psychology and neuroscience, therefore, she is also looking for projects related to neurodevelopmental disorders including autism and schizophrenia.
