Tonoy Emroz Alam (Bangladesh/Germany)

Languages: Bengali, English, Hindi, German

Tonoy is a contributor to the Mukto-Mona blog, a freethought movement, founded by murdered author Avijit Roy. Several other writers of the website were murdered by the Islamist terrorists.

He also wrote columns at major news outlets, where he has taken on controversial issues, championed equality and free inquiry, and aimed a critical eye at extremist religious beliefs and political ideologies. But as has become sadly predictable in the Islamic world, this has made him a target.

Being an Ex-Muslim atheist, he has closely seen how an overwhelming exaltation of ignorance in the Islamic world had led to an arrogant form of Islam, spreading across the landscape like a chronic disease. He believes that secularists are, therefore, burdened with a harrowing task: stopping the spread of ignorance while coping with the terrifying reality of violence and retaliation from extremists.

This sense of responsibility was the primary motive for him to join the Atheist Support Network – an Atheist Alliance International Program. In July 2021 he was elected to the AAI board.

Also in Minnesota, he was a co-founder and past board member of Camp Quest North, and a past board member of Humanists Minnesota.

In the United States, he has served on the national boards of directors of American Atheists and the Freedom From Religion Foundation (FFRF).

Internationally, he was a past vice president of Atheist Alliance International (AAI) before they split with Atheist Alliance of America and, as of 2023, is vice president of Atheist Alliance International (AAI) again. He frequently posts on the AAI Facebook page as the “Atheist Quora Astrologer”, with his humorous responses to astrological questions he finds on Quora.

He is the author of numerous pamphlets, and presentations such as “Atheism: A View of the World from the Ground Up” and “27 Reasons God-Belief is Dying”. He has been speaking about atheism to public and Christian high schools and universities for over 20 years.

For the past 20 years he has been the owner of the ATHEIST car license plate for Minnesota. His story about becoming an atheist is featured in the anthology Atheist Voices of Minnesota. He is proud to be listed in the reference book Who’s Who in Hell.

Secretary & Treasurer

Fotis Frangopoulos (Greece)

Languages: Greek, English

Fotis has a business administration background. He grew up paying little attention to religion as the majority in Greece does. He rejected Christianity in his late teens when he read about the way it was enforced by Roman emperors, how it destroyed the Hellenic civilization and established the Dark Ages. That marked a long period of unconcern during which he identified as non-religious and gradually found interest in secular issues.

By 2010 Fotis had gotten fed up of only words and theory but no action about state and church entanglement as well as the undeserved status and privileges that religions enjoy. He became a founding member of the Atheist Union of Greece (AUG) and served as president for 2013–2018.

He is the instigator and key operator of various AUG’s campaigns such as: the questionnaire and proposal to the political parties for the separation of Greek State and church, the conference for state-church relations, official complaints to authorities about the practice of illegally recording students’ religious views in public education and two litigations about the latter and the indoctrinating religious class taught in public schools.

In 2018, he edited, and the Union published, the “Dialogue about the Jerusalem Holy Light” about a Dark Ages scam that is nowadays indulged by the Greek government.

He first joined the AAI board in 2019 and undertakes various tasks and roles to increase the organization’s efficiency toward its vision and mission.

Regional Director, Australasia

Stella Thomas (Australia)

Languages: English

Stella is a board member of the Rationalist Society of Australia; she also has regular contact with the leadership of Humanists Australia and is the South Australian contact for the national grassroots group Fairness in Religion in Schools. Over the years, she has lobbied and provided submissions against religious privilege in various areas, such as; making public schools secular, marriage equality, voluntary assisted dying (voluntary euthanasia), removing prayer from public office, and the like. She also takes an interest in human rights, social justice, and environmental sustainability.

After a long and successful career in business management and accounts, in 2020, Stella commenced a Bachelor of Environmental Policy & Management (with a minor in politics); she is enjoying settling into this new direction.

Stella’s position is one of secularism and preventing religious privilege from dominating shared public spaces (laws, government, schools and institutions). Her approach is to listen to others and work towards common ground backed by evidence and reason. She says she doesn’t mind what supernatural beliefs others hold, as long as they do not cause harm, especially by way of undermining public policy and education.

Stella was born in Australia to Italian Catholic parents, for them religion was more of a cultural connection. At a very young age, there was occasional church and a few Sunday school lessons in preparation for her Communion. At Sunday school Stella’s questions were frowned upon, but she continued to ask them, and although she was not able to articulate it at the time, looking back, she says it was clear in her mind that the pressure of having blind faith was a path that she would not take.

Regional Director, Central & South America

Alfonso Ugarte Johnson (Bolivia)

Languages: Spanish, English

Alfonso is an independent, interdisciplinary artist and music teacher. He is trained as an architect and holds a Masters degree in Arts in Music Theatre from London’s Royal Central School of Speech and Drama.

Currently, in the audio social media app “Clubhouse”, he interviews renowned scientists and people who hold various spiritual beliefs. He practices Street Epistemology and facilitates conversations and debates between people of any and all beliefs. As a rationalist, he creates content with people from different religions and spiritual paths. His objective is to develop a deeply efficient and meaningful practice in communication.

During his life he has journeyed through several spiritual paths. As a four-year-old, he began traveling the world with his father in the Hare Krishna movement. During those early years, he spent time in South America and Sweden and, until the age of 8 donned the robes of a Hindu monk in Vrindaban, India. His mother tracked his whereabouts and brought him back to his homeland, Bolivia. As a deeply indoctrinated child, he longed for spirituality.

Three years after undergoing his first communion as a Catholic, at the age of 13, he found solace in Pentecostal evangelical Christianity. Fifteen years later, after an intense search, he found himself living inside a fantastic and scary spiritual narrative. In time, this led him to deconstruct and rebuild his model of reality.

His deep interest in science throughout the last twenty years has reinforced his steadfast belief in the impossibility of the existence of any god, soul, or consciousness beyond our bodies and brains.

Regional Director, Europe

Kristina Hallmeier (Germany)

Languages: German, English

Kristina Hallmeier is a convinced atheist and ardent humanitarian who strongly believes that atheism does not mean just the absence of something, but that an atheistic humanistic approach gives us the chance to build a society and world community with diverse perspectives and ideas. This must be based on mutual tolerance giving others the freedom to develop and grow instead of cutting others’ options and restricting all individual ambitions. Freedom of expression is paramount.

Kristina has worked with German human rights associations for many years and has worked as a volunteer with Atheist Alliance International since 2020.  Kristina now sees how human rights defenders are persecuted across the globe and how AAI is making a difference. This made her wish to contribute to the organization more actively. In May 2022, Kristina was elected as the AAI Regional Director, Europe.

Regional Director, North America

Christine Shellska (Canada)

Languages: English

Christine became an atheist activist in 2010 when her studies led her to attend her first conference. Having grown up in a context where atheism was normalized, she was shocked to learn how pervasive religion remains.

As a Ph.D. Candidate at the University of Calgary, she studied the rhetorical strategies employed by the Intelligent Design Creationism movement. Her areas of focus included history, philosophy and sociology of science, Actor Network Theory, and rhetoric.

Among other involvement in the secular community, she is a former Director of the American Humanist Association, the Humanist Society, and Atheist Alliance International. In the latter capacity, she addressed the UN, condemning the mistreatment of LGBTQ+ people, female genital mutilation, and religious discrimination in accessing science-based education, health care, and social services. She has delivered presentations at local venues (including guest lectures and debates), as well as at prominent conferences in Canada and the US, on various topics of interest to skeptics, humanists, secularists, and activists.
