March 2024: Merike Kaeo joins our Advisory Board

I am extremely honored to welcome Merike Kaeo as a new member of our Editorial Advisory Board. Merike has extensive experience in all aspects of network and information security, and I look forward to working with her on developing article topics for IPJ.

Pindar Wong has served on our Editorial Advisory Board since the inception of this journal. I have always appreciated his invaluable insight and advice, particularly on emerging technologies such as Blockchain. Pindar has indicated that he is moving on to pursue other interests and wishes to step down from his advisory role. I thank Pindar for all his contributions and wish him the best in his future endeavors.
