Diver since 1999, specialized in underwater photography and video, has won several national and international awards.
The taste for deep dives, unexplored wrecks and caves, lead Armando Ribeiro to create the 1st team of technical divers that use closed circuit rebreathers (CCR) in Portugal. Created in 2004/2005 the In-Silence Dive Team has as main objectives the development of CCR diving, the exploration off deep shipwrecks and caves on the Portuguese coast and the participation in international diving expeditions. Armando quickly became one of the first serious advanced expedition divers in Portugal, taking part in numerous adventures with some of the world’s best technical divers.
His most recent project aims to explore, obtain cave’s cartography and capture in video the biggest springs in Portugal. This exciting adventure was recently renewed by the discovery of new galleries that open the door to new challenges due to the greater depts and distance that can be achieved. The expeditions and projects impact, through the publication of articles in diving magazines and the national and international public projection of their videos, had a strong recognition in the national diving community, being already a reference in all expos and events related to technical diving.

Aviad Cahana invented and developed the Avelo System, a revolutionary scuba system that is both lightweight and redefines how divers manage buoyancy. His diving career began as an instructor in the Red Sea where he also worked as a dive guide and trip leader for destination trips. Aviad has been diving for more than 28 years with experience in technical diving and other specialties.
After teaching scuba while undertaking a solo world-cycling expedition, Aviad returned to teaching scuba in the Red Sea where his significant other gently encouraged him to go get a real job.
Aviad is an environmental and chemical engineer with education from the Israeli Institute of Technology and in the United States. He has worked as CTO and CEO of a technology startup in the renewable energy and renewable chemical industry.
Aviad first developed the concept for the Avelo System in Maui by questioning the need for heavy gear and investigating ways to improve heavy and cumbersome dive equipment. He then created Avelo Labs and as CEO of Avelo is introducing the world to a new way of scuba diving.

He led the design, development, and manufacture of numerous scientific and exploratory inventions including closed-cycle life support systems, autonomous ground and sub-ice underwater vehicles; ice penetrating cryobots; and high energy optical waveguided power transmission. Since 2003 he was PI or Co-I of the NASA field robotics systems: ARTEMIS [NNX14AC01G] (first AUV to undertake long distance exploration under the McMurdo Ice Shelf in Antarctica, 2015); ENDURANCE [NNX07AM88G] (first sub-glacial lake exploration robot, 2008); VALKYRIE [NNX11AJ89G] (first laser-powered cryobot, 2014); and DEPTHX [NNG04GC09G] (autonomously explored the world’s deepest hydrothermal spring and discovered 4 new bacterial phyla, 2007). He is the chief architect of the Stone Aerospace SUNFISH AUV. Dr.
Stone was PI or Co-I on eight NASA field campaigns. All of those field campaigns were conducted with novel robotic systems in demanding settings with zero accidents and the teams all returned safely, as did all of the vehicles. During the past 5 years Dr. Stone has successfully directed the SPINDLE [NNX15AT32G], ARCHIMEDES [NNX17AF64G], and THOR [80NSSC18K1738] projects for the NASA Ocean Worlds program and is the PI for the SESAME project PROMETHEUS [80NSSC19K0612], all of which deal with technologies to enable Ocean World planetary missions.

Brandi Mueller is a photographer and writer obsessed with traveling and sharing the stories of what she sees. Learning to dive when she was 15 as a foreign exchange student in New Zealand, Brandi became a diving professional at 20 and a captain at 24. She studied marine biology in college and has a Master’s degree from the University of Hawaii.
Working on liveaboards around the world (and traveling other places to dive on her vacations) she started to take photos and collected tips and tricks from any photographers she met, eventually meeting a few editors willing to publish some of her work.
WWII wrecks are some of her favorite subjects and she is a captain of the M/V Truk Odyssey liveaboard which dives the Japanese WWII wrecks of Chuuk (Truk Lagoon.) But you can also find her with a macro lens photographing nudibranchs that live on the wrecks. She finds capturing the behavior of small critters just as exciting as tiger sharks or an airplane wreck.
Brandi continues to dive around the world with the intent to share images and stories of the people, animals and wrecks that live around the water and below. One of her current projects involves ocean environments and communities likely to be impacted by climate change with hopes of those images and words inspiring empathy and protection of those places.
Brandi has won several awards and is widely published in books, magazines, online and has a book called The Airplane Graveyard. She is an Ikelite Ambassador, is part of the Ocean Artists Society and a Platinum Pro 5000 recipient.

Gareth Lock is the owner & founder of The Human Diver, an organisation formed to bring human factors knowledge, experience and practice from high-risk domains and academia into the sport of diving. Since January 2016 when he formed the company, he has taught hundreds of people in face-to-face classes around the world and thousands via online and webinar-based programmes. He has published Under Pressure: Diving Deeper with Human Factors, the only textbook that looks at this topic and in May 2019, released ‘If Only…’ which looks at a tragic diving accident through the lenses of human factors and a Just Culture. Over the last 3 years he has also led two reviews of fatal military diving accidents on behalf of Defence departments, applying systems thinking and human factors.
Recognising that the need for human factors is greater than one person can deliver, he has also trained ten instructors to deliver Human Diver materials around the globe and is working with two agencies to incorporate human factors concepts and tools into instructor development and diver training materials.
The Human Diver website is https://www.thehumandiver.com where you can find everything you want to know about HF in Diving and associated training materials.

1974 marked the first dive of JC in a cold and dark Swiss lake, he was 14. It took him another 12 years to turn into a dive professional.
In 1986, JC decided to leave the corporate 9-5 and Swiss comfort to follow the dream of working as a diving professional in the Maldives. This passion changed the curse of his life for ever (like for many people that JC transformed the life in his career).
After climbing the stairs of a prominent diving organization and being a CEO for over 20 years, he continued to dedicate his passion to help SSI – Scuba Schools International to change the approach, and moved completely to a digital version of the programs, which certainly helped to change the approach of the diving education.
Monachon’s function as an International Business Development specialist gave this unstoppable traveler the opportunity to speak 5 languages and identify the needs in various market places. A typical example would be the launching of a Mermaid Program that nobody would have seen as a boost for the industry.
Scuba Diving education is one aspect of his career and his favorite claim is that better to take imperfect action than inaction.
Monachon’s aim is to stay as close as possible to local communities and market places, find ways to improve their marketing while using social media marketing organically, in which he has specialized over the past three years helping to develop specific webinars. He personally conducted over 423 webinars in 5 languages in the past 24 months.
Diving is covering all great market demands – relationship, health and wealth. It’s not a trend activity and that’s why the future can be seen with an optimistic view.
