What is the most important piece of advice you give students to help them succeed?
Do not be afraid to challenge traditionally held beliefs or dogmas in your field. Science is ever changing. Fifty percent of what you know is probably wrong. Our job as scientists and researchers is to try to figure out which 50% is which. Until it is disproven, accept that for which the evidence appears solid and logical and is free of covert or conflicts of interest. Do not ever dismiss lightly that for which there is credible evidence. Question everything else. Eventually the truth will always prevail. So always aim to be on the side of truth.
