My name is Sachchidanand R. Swami or in short Sachin R. Swami. I'm a human behavior researcher, analyst, profiler and the chief writer of this website. I'm one of the very few individuals from India and/or Indian sub-continent to hold two internationally acclaimed human intelligence (humint) certificates, first for the facial micro-expressions detection with Expert level and second for the facial subtle expressions detection with Proficient level.

Also, this website has been ranked under the (World's) 10 Best Body Language Bloggs and Websites, voted twice by the international readers and subscribers of the world’s most popular news aggregator application Feedly since August 2021. It has been ranked along with websites and blogs run by Dr. Paul Ekman (Group), Dr. David Matsumoto, Dr. Jack Brown, Patti Wood and Renee Ellory.

I've a considerable amount of experience in behavioral analysis, behavioral profiling and behavioral prediction by using some of the basic principles, rules and facts from human biology, ecology, ethology, sociology, physiology, psychology, evolution, neuroscience and (classical) physics. Methodological, systematic and thorough analysis is my specialty.

I began exploring, studying, analyzing and profiling human behavior since year 2004 through observing and watching with tribal, rural, urban and metropolitan populations in real-time and through videos. Verbal interactions with people also has been helping me a lot.

"Sachchidanand (himself) wouldn't admit publicly but (according to me) he is one of the world's top 20 nonverbal communication experts."

Although I've studied, researched and written about different topics of human (social) behavior, body language and nonverbal communication; detecting or picking facial micro-expressions, facial compound expressions, facial subtle-expressions and tiny or subtle variations in well-known, established and recognized cues are my areas of great interest, attention and specialty.

I actively and passionately engage myself in critical case studies, behavioral predictions and personality profiling. Also, I voluntarily, regularly and extensively interact, communicate and share my articles, insights and observations with many academies, institutions, universities, educators, trainers and field experts on a regular basis through email.

Many articles published on this website have been cited (used and mentioned as reference) by students, fellows, faculty members, teachers, lecturers and researchers in their own literature, including Post-Doctoral, Doctoral (Ph. D.), Master and Bachelor thesis, from following universities, academies, institutions, schools and programs:

Many internationally acclaimed, reputed, popular, well-known, best-selling and famous body language experts, behavioral researchers, behavioral profilers, behavioral (meta-)analysts, psychologists, self-help practitioners, bloggers, authors, writers, counselors, instructors, trainers and educators know me and/or follow me in person and/or are connected with me.

Many of them have been duly recognizing and appreciating my insights and observations by replying to emails and commenting on posts on social media, including Mark Bowden and Chase Hughes (Team). This has greatly helped in giving my best every time I convey something to readers about my findings, observations, inputs and insights.

The world's leading, well respected and critically proven Nonverbal Communication expert and my Guru Sir Joe Navarro (retired special agent, counter-intelligence supervisor and spy-catcher who served in the Federal Bureau of Investigation (FBI) for 25 years) has been a great source of guidance, inspiration and additional insights.
