He produced and hosted the 10-part documentary series Tattoo Hunter on the Discovery Channel, which traveled the indigenous world to showcase vanishing art forms of body modification.

[4] His PhD studies at Arizona State University (2005–2009) focused on the socioeconomic impacts of tourism on the Rarámuri (Tarahumara) people of Mexico's Copper Canyon region.

With an introduction provided by tattooed Kalinga elder Ms. Natividad Sugguiyao, this book is the first volume to focus on the indelible arts of these Cordilleran people and is based on field research conducted in 2007 and 2008.

He also wears approximately one thousand razor and knife-cut scars across his body received from other groups like the Kaningara of Papua New Guinea, Bétamaribé of Benin, the Hamar of Ethiopia, and the Makonde of Mozambique.

Based on one decade of Dr. Krutak's field research among animistic and shamanic societies of Asia, Africa, the Americas, and Melanesia, Magical Tattoos and Scarification journeys into highly sacred territory to reveal how people utilize ritual body modification to enhance their access to the supernatural.

In 2020, Krutak with Dr. Dario Piombino-Mascali co-authored a peer reviewed book chapter on global Indigenous therapeutic tattooing in relation to the Iceman in the tome Purposeful Pain: The Bioarchaeology of Intentional Suffering published by Springer.

Krutak also serves as an Executive Producer for the forthcoming (2024) film documentary Treasure of the Rice Terraces, which chronicles the story behind Filipino identity in relation to the tattoo revival of the Kalinga people of northern Luzon.

Numerous years elapsed before a woman acquired a full complement of tattoos that identified her family and clan group genealogy, social endeavors, and sometimes the achievements of relatives.

For example, tattoos placed over the sternum were believed to alleviate heart trouble, two small lines placed close to the eyes, temple, and forehead, might remedy headache or vision problems.

[20] Krutak's tattoo research is regularly shared with local communities when his projects and publications are completed, so that future generations have the necessary resources to revive, as needed, these ancient customs.

After his Master's research in Alaska, he provided copies of his unpublished thesis to local Bering Strait libraries, organizations, families, and regional universities so this indelible history could be revisited at any time.
