Expert is a recognized authority worldwide on hydroponics. He presents information on hydroponic culture of various vegetable crops. In addition, he has written five books on hydroponic culture both for commercial growers and backyard hobbyists. While a graduate student, he was asked by a private group to assist them in the construction of hydroponic greenhouses in the Vancouver area. He continued with outside work in greenhouses and soon was asked to conduct evening extension courses in hydroponics.

Upon graduation with his doctorate degree in Horticulture in 1975 he became Urban Horticulturist for the Faculty of Plant Science. He held that position for three years before the call of commercial hydroponics took him to many projects in countries such as Venezuela, Taiwan, Saudi Arabia, the United States and in 1999 to Anguilla, B.W.I, in the Eastern Caribbean.

While in the position of Urban Horticulturist, expert taught courses in horticulture, hydroponics, plant propagation, greenhouse design and production. During this period while Urban Horticulturist and later General Manager for a large plant nursery, he continued doing research and production consultation for a commercial hydroponic farm growing lettuce, watercress and other vegetables in Venezuela. Later during 1995 to 1996, he became project manager for the Venezuelan farm to develop hydroponic culture of lettuce, watercress, peppers, tomatoes and European cucumbers using a special medium of rice hulls and coco coir from local sources. He also designed and constructed a Mung bean and alfalfa sprout facility to introduce sprouts into the local market.

Expert worked with a company in Florida in the growing of lettuce in a floating raft culture systems the Technical Director and Project Manager for hydroponic projects in the growing of watercress and herbs in California. He designed and constructed several 3-acre outdoor hydroponic watercress facilities using a unique NFT system. These overcame production losses due to drought conditions in the area.
From there expert became the Hydroponic Greenhouse Farm Manager for the first Hydroponic Farm associated with a high-end resort, CuisinArt Resort & Spa, in Anguilla, B.W.I. in the northeastern Caribbean. The hydroponic farm is unique in being the only one in the world owned by a resort growing its own fresh salad crops and herbs exclusively for the resort. This farm has become a key component of the resort in attracting guests to experience real home-grown type of vegetables, including tomatoes, cucumbers, peppers, lettuce, bok choy and herbs. The resort, together with its Hydroponic Farm, has gained world-wide recognition as one of the leading hotels of the world.

Expert continues to do consulting on many unique hydroponic greenhouse operations such as Lufa Farms in Montreal, Canada. There he established the growing techniques and hydroponic systems for a rooftop hydroponic greenhouse in downtown Montreal. All vegetables are marketed through a community supported agriculture (CSA) program.
