Successful Interaction in the Attorney-Forensic Chemical Expert Dyad

How can attorneys and experts best support one another?

“Dyad” is defined as ‘something that consists of two elements or parts’. The successful attorney- chemical expert “dyad” is, in my opinion, critically dependent on creating a trusting, workable, two-way communication. The expert must be able to educate the attorney in the complexities of the subject case, so that the attorney is comfortable in mediation or court procedures.. … Continue Reading
