Пятнадцать минут.Каждый день.

  1. 1

    Урок влезает в обеденный перерыв

    По одной мысли за раз, на коротких слайдах. Весь урок — около пятнадцати минут.

  2. 2

    Практика с мгновенной обратной связью

    Вопросы — внутри урока. Отвечаете и сразу видите, получилось ли.

  3. 3

    Стрик, который возвращает вас снова

    Урок в день держит стрик. Короткие регулярные занятия доводят до конца курса.

Для будущих учёных и клиницистов.

  • Студенты-биологи после вводного курса

    Где вы вырастете сильнее всего

    Проследите путь гена от ДНК до белка

    Этап 2 · Genome & Gene Expression
  • Будущие медики, которым нужен механизм

    Где вы вырастете сильнее всего

    Расшифровывайте сигналинг, деление и гибель клетки

    Этап 5 · Signaling, Division & Fate
  • Лаборанты, которые спрашивают, почему работает протокол

    Где вы вырастете сильнее всего

    Проектируйте эксперименты с правильными контролями

    Этап 6 · Methods & Case Studies

Куда ведёт этот курс.

Работа, вокруг которой построен курс, и как в неё попадают.

Research Associate

Ставит эксперименты в исследовательской или биотех-лаборатории и держит данные в порядке.

Все карьеры будущего

В работе

  • Работать с клеточными культурами, ПЦР и другими базовыми лабораторными методами
  • Записывать каждый шаг, чтобы эксперимент можно было повторить
  • Анализировать результаты и представлять их команде

Как туда попадают

Для лабораторных ролей стандарт — диплом по биологии или смежной науке.

Будьте первыми в очереди.

Ранний доступ — для частных лиц, пилот — для команд. Расскажите, кто у вас учится.
