Congratulations to Ir. Dave Mangindaan, PhD, MRSC, AMIChemE, IPM for achieving h-index of 9, looking forward for h-index of 10!

H-index is a parameter that measures not just the quantity, but also the quality of publication performance of an academic.

In this case, h=9 means that an author has at least 9 papers, that are cited at least 9 times for each of them.
