Congratulations to Ir. Dave Mangindaan, PhD, MRSC, AMIChemE, IPM for achieving h-index of 11, looking forward for achieving h-index of 12!

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=11 means that an author has at least 11 papers, that are cited at least 11 times for each of them.
